Change subject: IMPALA-10811 RPC to submit query getting stuck for AWS NLB forever. ...................................................................... IMPALA-10811 RPC to submit query getting stuck for AWS NLB forever. This patch addresses Impala client hang due to AWS network load balancer timeout. Tthe scope of the fix is applicable to the following Impala clients. 1. HS2 2. Beeswax 3. Impyla 4. HUE These clients issue thrift RPC ExecuteStatement() followed by repeated call to GetOperationStatus() (HS2, Impyla and HUE) or a variant of it (Beeswax) to Impala backend. In the fix, the backend operation for ExecuteStatement() runs asynchronously and its completion status is checked repeatedly via the equivalent of the GetOperationStatus() from the client. A new execution state CATALOG_OP_RUNNING is added to represent the new execution state.
