Lars Volker created IMPALA-8380:
-----------------------------------

             Summary: The minicluster metastore doesn't start on systems with 
postgres 10
                 Key: IMPALA-8380
                 URL: https://issues.apache.org/jira/browse/IMPALA-8380
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 3.3.0
            Reporter: Lars Volker


We currently hardcode the postgres client version in at least 2 places:

{noformat}
$ git grep 9.0-801
bin/impala-config.sh:129:export IMPALA_POSTGRES_JDBC_DRIVER_VERSION=9.0-801
fe/pom.xml:425:      <version>9.0-801.jdbc4</version>
{noformat}

Apparently version 9 of the JDBC driver doesn't support connecting to postgres 
10 ([Some info 
here|https://github.com/brettwooldridge/HikariCP/issues/1103#issuecomment-369767801]).
 We should upgrade to v42+.
