New in This Release
IMPORTANT The Pig-0.16
MEP-6.3.0 release is designed to work with Hive-2.3.6 MEP-6.3.0 and
contains a fix that adds com.mapr.web.security.SslConfig class to Pig classpath. This fix
allows Pig-0.16 MEP-6.3.0 to be successfully integrated with Hive-2.3.6 MEP-6.3.0 when
HCatalog is used. If you use Hive-2.3.6 MEP-6.3.0 with older Pig-0.16 releases, this may
cause an exception when HCatalog is used:
Caused by: java.lang.ClassNotFoundException:
com.mapr.web.security.SslConfig$SslConfigScope
