If NUM_NODES is set to a value other than 0 or 1 below error is raised ERROR: Invalid value for query option NUM_NODES: <value> is not in range [0, 1] Change-Id: Ib283ae350875a7ac217490c216a26281f1bb4812 Reviewed-on: http://gerrit.cloudera.org:8080/21147 Reviewed-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> > Raise error when NUM_NODES is set to a value other than 0 or 1 > -------------------------------------------------------------- > > Key: IMPALA-11938 > URL: https://issues.apache.org/jira/browse/IMPALA-11938 > Project: IMPALA > Issue Type: Bug > Reporter: Zoltán Borók-Nagy > Assignee: Anshula Jain > Priority: Major > Labels: newbie, ramp-up > > Since IMPALA-4746 is not implemented there is basically two modes of Impala > to execute queries: > * NUM_NODES = 0 > ** create a distributed plan and execute the query on as many executors as > possible > * NUM_NODES = 1 > ** create a single node plan and execute the query on the coordinator > But currently users can specify any value to NUM_NODES, e.g. 42, but the > behavior they get would correspond to the NUM_NODES = 0 case (distributed > mode). > Impala should raise an error when NUM_NODES is set to other value than 0 or 1 > so users won't have wrong assumptions. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
