Description

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.

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)

This happens because of the following bit:

    // 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");
    }

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.
