0 means 'unlimited'. Defaults to exclusive. Arguments: If true, permits the removal of a data directory that is configured for use by existing tablets. insert overwrite table main_table partition (c,d) select t2.a, t2.b, t2.c,t2.d from staging_table t2 left outer join main_table t1 on t1.a=t2.a; In the above example, the main_table & the staging_table are partitioned using the (c,d) keys. Defaults to inclusive. {"startCluster":{}} table, view, synonym), not just indexes. kudu table locate_row [-check_row_existence] 1. kudu tserver run [-tserver_master_addrs=] [-fs_wal_dir=] [-fs_data_dirs=] [-fs_metadata_dir=] [-block_cache_capacity_mb=] [-memory_limit_hard_bytes=] [-log_dir=] [-logtostderr] If the measured cross-location load imbalance for a table is greater than the specified threshold, the rebalancer tries to move table’s replicas to reduce the imbalance. The most common configuration flags are described below. ), move_replicas_from_ignored_tservers (optional). To drop an index in Oracle SQL, you use the DROP command. One of 'json', 'json_compact' or 'table'. Whether to create the destination table if it doesn’t exist. If blank, the leader chooses its own successor, attempting to transfer leadership as soon as possible. kudu master dump_memtrackers [-format=] [-memtracker_output=] [-timeout_ms=] kudu fs check [-fs_data_dirs=] [-fs_metadata_dir=] [-fs_wal_dir=] [-repair] kudu pbc edit [-nobackup] '[">=", "col1", "value"]' replicas of tablets of replication factor 1). The auto-created table is dropped upon successful completion of the test if not overridden by the '--keep_auto_table' flag. DELETE t1 FROM kudu_table t1 JOIN non_kudu_table t2 ON t1.x = t2.x; -- The tables can be joined in any order as long as the Kudu table -- is specified as the deletion target. Arguments: Tablet identifier pattern. The value of 'auto' means turn it on/off depending on the replica management scheme and Kudu version. This will be faster also because you do not need to drop/create table. If the table name is different, the table is renamed in Kudu to match the HMS. Size of the error buffer, per session (bytes). Dropping a Kudu table using Impala. open sourced and fully supported by Cloudera with an enterprise subscription Arguments: Comma-separated list of directories with data blocks. For all the configuration options pass --helpfull or see https://kudu.apache.org/docs/configuration_reference.html#kudu-tserver_supported If the table was created as an internal table in Impala, using CREATE TABLE, the standard DROP TABLE syntax drops the underlying Kudu table and all its data. Data Model. Set to 0 to disable. The rebalancing tool moves tablet replicas between tablet servers, in the same manner as the 'kudu tablet change_config move_replica' command, attempting to balance the count of replicas per table on each tablet server, and after that attempting to balance the total number of replicas per tablet server. If the table was created as an internal table in Impala, using. If the table was created as an external table, using CREATE EXTERNAL TABLE, the mapping between Impala and Kudu is dropped, but the Kudu table is left intact, with all its data. I couldn't find any operation for truncate table within KuduClient. Usage: For all the configuration options pass --helpfull or see https://kudu.apache.org/docs/configuration_reference.html#kudu-master_supported A Kudu table containing a dot is considered as a schema/table combination, e.g. If the designated successor cannot catch up to the leader within one election timeout, leadership transfer will not occur. Whether to use random numbers instead of sequential ones for primary key columns. 'json_pretty' produces pretty-printed json. Usage: Whether to move replicas from the specified 'ignored_tservers' to other servers when the source tablet server is healthy. The other valid values are 'always' or 'never'. For both ways see below for more details. Port may be omitted if the Tablet Server is bound to the default port. Arguments: String representation of lower bound of the table range partition as a JSON array, String representation of upper bound of the table range partition as a JSON array. The easiest method (with shortest code) to do this as mentioned in the documentaion is read the id (or all the primary keys) as dataframe and pass this to KuduContext.deleteRows.. import org.apache.kudu.spark.kudu._ val kuduMasters = Seq("kudu… Usage: Usage: Arguments: Comma-separated list of column fields to include in output tables. UUIDs of tablet servers to ignore while rebalancing the cluster (comma-separated list). Whether to fill block cache when scanning. The only supported predicate operator is AND. The number of hash partitions to create when this tool creates a new table. kudu table column_remove_default SQL DROP TABLE Example. is this for being created with impala? Usage: kudu perf tablet_scan [-fs_data_dirs=] [-fs_metadata_dir=] [-fs_wal_dir=] [-num_iters=] [-ordered_scan] Arguments: Scan rows from an existing table. kudu table add_range_partition [-lower_bound_type=] [-upper_bound_type=] #12 0x0000000000524338 in PyEval_EvalFrameEx () No symbol table info available. It replaces the unrecoverable tablet with a new empty one representing the same partition. Possible values: uuid, rpc-addresses, http-addresses, version, seqno, heartbeat, start_time, state. Arguments: If true, performs the action on the tserver even if it has not been registered with the master and has no existing tserver state records associated with it. 'plain_full' is plain text with all results included. false. Flink Kudu Connector. kudu local_replica cmeta set_term [-fs_data_dirs=] [-fs_metadata_dir=] [-fs_wal_dir=] kudu table column_set_compression But I am facing one issue when I create a view by doing a UNION ALL of HDFS/S3 stored as parquet and Kudu tables. Starting with Kudu 1.12.0, it is not required to run this tool to add or remove directories. In other words, the customers table is not placed into the recycle bin and, therefore, can not be recovered later if required.
