[jira] [Created] (HIVE-10267) HIVE-9664 makes hive depend on
ivysettings.xml
Sushanth Sowmyan created HIVE-10267:
---------------------------------------
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.
