Wenzhe Zhou has uploaded a new patch set (#4). ( http://gerrit.cloudera.org:8080/21458 )
Change subject: IMPALA-13107: Don't start query on executor if instance number equals 0 ...................................................................... IMPALA-13107: Don't start query on executor if instance number equals 0 In bad networking condition, TExecPlanFragmentInfo in KRPC messages received by executors could be truncated due to KRPC failures, but truncation may not cause thrift deserialization error. The invalid TExecPlanFragmentInfo causes Impala daemon to crash. To avoid crash, this patch checks number of instances in received TExecPlanFragment on executor. The query will not be started if number of instances equals 0. Also adds DCHECK on coordinator side to make sure it does not send TExecPlanFragment without any instance. Testing: - Passed core tests.
