Philip Zeyliger created IMPALA-7091:
---------------------------------------
Summary: Occasional errors with failure.test_failpoints.TestFailpoints.test_failpoints in hbase tests
Key: IMPALA-7091
URL: https://issues.apache.org/jira/browse/IMPALA-7091
Project: IMPALA
Issue Type: Task
Components: Frontend
Reporter: Philip Zeyliger
Assignee: Philip Zeyliger
When running the following test with "test-with-docker", I sometimes (but not always) see it fail.
{code:java}
failure.test_failpoints.TestFailpoints.test_failpoints[table_format: hbase/none | exec_option: {'batch_size': 0, 'num_nodes': 0, 'disable_codegen_rows_threshold': 0, 'disable_codegen': False, 'abort_on_error': 1, 'debug_action': None, 'exec_single_node_rows_threshold': 0} | mt_dop: 4 | location: OPEN | action: MEM_LIMIT_EXCEEDED | query: select * from alltypessmall union all select * from alltypessmall]{code}
The error I see is an NPE, and, correlating some logs, I think it's this:

The test-with-docker stuff starts HBase at run time independently of data load in a way that our other tests don't, and I suspect HBase simply hasn't loaded the tables.
I have a change forthcoming to address this.
