---------------------------------------

             Summary: HIVE-9664 makes hive depend on ivysettings.xml
                 Key: HIVE-10267
                 URL: https://issues.apache.org/jira/browse/HIVE-10267
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Sushanth Sowmyan
            Assignee: Anant Nag


HIVE-9664 makes hive depend on the existence of ivysettings.xml, and if it is not present,
it makes hive NPE when instantiating a CLISessionState.

{noformat}
java.lang.NullPointerException
at org.apache.hadoop.hive.ql.session.DependencyResolver.<init>(DependencyResolver.java:61)
at org.apache.hadoop.hive.ql.session.SessionState.<init>(SessionState.java:343)
at org.apache.hadoop.hive.ql.session.SessionState.<init>(SessionState.java:334)
at org.apache.hadoop.hive.cli.CliSessionState.<init>(CliSessionState.java:60)
{noformat}

This happens because of the following bit:

{noformat}
    // If HIVE_HOME is not defined or file is not found in HIVE_HOME/conf then load default
ivysettings.xml from class loader
    if (ivysettingsPath == null || !(new File(ivysettingsPath).exists())) {
      ivysettingsPath = ClassLoader.getSystemResource("ivysettings.xml").getFile();
      _console.printInfo("ivysettings.xml file not found in HIVE_HOME or HIVE_CONF_DIR," +
ivysettingsPath + " will be used");
    }
{noformat}

This makes it so that an attempt to instantiate CliSessionState without an ivysettings.xml
file will cause hive to fail with an NPE. Hive should not have a hard dependency on a ivysettings,xml
being present, and this feature should gracefully fail in that case instead.
