---------------------------------------
Summary: lock_max_wait_time_s is not set for ComputeStats
Key: IMPALA-12779
URL: https://issues.apache.org/jira/browse/IMPALA-12779
Project: IMPALA
Issue Type: Bug
Reporter: Quanlong Huang
While showing non-default options in the /operations webUI of catalogd, I found
ComputeStats statements all have lock_max_wait_time_s=0. The default value is
300.
Should we set the default value (300) in TDdlQueryOptions? [~boroknagyz]
{noformat}
// Subset of query options passed to DDL operations
struct TDdlQueryOptions {
// True if SYNC_DDL is set in query options
1: required bool sync_ddl
// Passes the debug actions to catalogd if the query option is set.
2: optional string debug_action
// Maximum wait time on an HMS ACID lock in seconds.
3: optional i32 lock_max_wait_time_s
// The reservation time (in seconds) for deleted impala-managed kudu table.
// During this time deleted Kudu tables can be recovered by Kudu's 'recall
table' API.
// See KUDU-3326 for details.
4: optional i32 kudu_table_reserve_seconds

We set the default value in TQueryOptions:
