IMPALA-9199 adds "ECONNRESET, // 104: Connection reset by peer"
> Blacklist additional posix error codes for failed DataStreamService RPCs

> Key: IMPALA-9253
> URL: https://issues.apache.org/jira/browse/IMPALA-9253
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Sahil Takiar
> Priority: Major
>
> Filing as a follow up to
> [IMPALA-9137|http://issues.cloudera.org/browse/IMPALA-9137],
> [IMPALA-9137|http://issues.cloudera.org/browse/IMPALA-9137] blacklists a node
> if a RPC fails with specific posix error codes:
> * 107 = ENOTCONN: Transport endpoint is not connected
> * 108 = ESHUTDOWN: Cannot send after transport endpoint shutdown
> * 111 = ECONNREFUSED: Connection refused
> These codes were produced by running a query, killing a node running that
> query, and then seeing what error codes the query failed with.
> There may be other error codes that are worth using for node blacklisting as
> well. One way to come up with more error codes is to use iptables to
> introduce network faults between Impala processes and see how RPCs fail.
