Vihang Karajgaonkar has uploaded a new patch set (#5). ( http://gerrit.cloudera.org:8080/16548 )
Change subject: IMPALA-10219: Expose DEBUG_ACTION query option in catalog ...................................................................... IMPALA-10219: Expose DEBUG_ACTION query option in catalog This patches enables DEBUG_ACTION in the catalog service's java code. Specifically, DEBUG_ACTION query option is now exposed to TResetMetadataRequest and TExecDdlRequest so that we can inject delays while executing refresh or ddl statements. For example, 1. To inject a delay of 100ms per HDFS list operation during refresh statement set the following query option: set debug_action=catalogd_refresh_hdfs_listing_delay:SLEEP@100; 2. To inject a delay of 100ms in alter table recover partitions statement: set debug_action=catalogd_table_recover_delay:SLEEP@100; 3. To inject a delay of 100ms in compute stats statement set debug_action=catalogd_update_stats_delay:SLEEP@100; Note that this option only adds the delay during the update_stats phase of the compute stats execution. Testing: 1. Added a test which sets the query option and makes sure that command takes more time than without query option. 2. Added unit tests for the debugAction implementation logic.
