------------------------------------
Summary: Invalid TExecPlanFragmentInfo received by executor with
instance number as 0
Key: IMPALA-13107
URL: https://issues.apache.org/jira/browse/IMPALA-13107
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Wenzhe Zhou
Assignee: Wenzhe Zhou
In a customer report case, TExecPlanFragmentInfo received by executors with
instance number as 0, like
{code:java}
impalad.executor.net.impala.log.INFO.20240522-160138.197583:I0523
00:59:16.892853 199528 control-service.cc:148]
624c47e9264ebb62:5aa89af300000000] ExecQueryFInstances():
query_id=624c47e9264ebb62:5aa89af300000000 coord=coordinator.net:27000
#instances=0
{code}
It seems KRPC messages were truncated due to KRPC failures, but truncation may
not cause thrift deserialization error. The invalid TExecPlanFragmentInfo
causes Impala daemon to crash.
