Sahil Takiar created IMPALA-9253: ------------------------------------ Summary: 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: Improvement Reporter: Sahil Takiar
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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
