If true, dumps rowset metadata before dumping data. If not provided, one is generated. Should the checksum scanner use a snapshot scan? e.g. true|1|yes|decoded = print them decoded Its primary use is to jettison an unrecoverable tablet in order to make the rest of the table available. Usage: Arguments: UUID of the tablet server hosting the existing replica. Note: The members of the new Raft config must be a subset of (or the same as) the members of the existing committed Raft config. 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. Usage: kudu local_replica delete [-fs_data_dirs=] [-fs_metadata_dir=

Arguments: Comma-separated list of column fields to include in output tables. log messages go to stderr instead of logfiles. The type of the lower bound, either inclusive or exclusive. kudu tablet change_config remove_replica {"createCluster":{"numTservers":3}} Table output flattens the memtracker hierarchy. Alternatively, the tool can create the new table using the same table and partition schema as the source table. This setting is effective only if the '--ignored_tservers' flag is specified as well. If left empty, then auto-generated strings of length specified by the '--string_len' parameter are used instead. Existing replica’s new type. This can be useful to check for row count skew across different tablets, or whether there is a long latency tail when scanning different tables. Tables created with a specified LOCATION are considered unmanaged by the metastore. The original tablet will be deleted. Neither the existing table nor its data is ever dropped/deleted. https://kudu.apache.org/docs/configuration_reference.html#kudu-master_supported, https://kudu.apache.org/docs/configuration_reference.html#kudu-tserver_supported. kudu pbc edit [-nobackup] kudu local_replica cmeta rewrite_raft_config …​ [-fs_data_dirs=] [-fs_metadata_dir=] [-fs_wal_dir=] The threshold represents a policy wrt what to prefer: either ideal balance of the cross-location load on per-table basis (lower threshold value) or minimum number of replica movements between locations (greater threshold value).

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. My guess is that Kudu doesn't have enough memory, sometimes CM can configure it to use 1GB which is below the safe minimum.

So if you accidentally run your rollback script in production, you can get going again :) Arguments: Usage: This will be faster also because you do not need to drop/create table. Arguments: Usage: If not set, the configuration from the Kudu master is used, so this flag should not be overriden in typical situations. Fixing placement policy violations involves moving tablet replicas across different locations of the cluster. UUID of the server that leadership should be transferred to. In Kudu, doing a delete like this is basically like inserting as many rows as you are deleting, so this might not be what you want to do.
