------------------------------------
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.
