(Updated June 20, 2014, 8:55 p.m.) Review request for hive. Bugs: HIVE-7167 https://issues.apache.org/jira/browse/HIVE-7167 Repository: hive-git Description ------- In the case that hiveserver2 uses embedded metastore and hiveserver uses remote metastore, this exception comes up when hiveserver2 and hiveserver are started simultaneously. See the bug link: https://issues.apache.org/jira/browse/HIVE-7167 The idea is to catch JDOException from concurrent defaultDB and roles initializations or privilege insertions, and try createDefaultDB, createDefaultRoles and addAdminUsers one more time, if still fails, simply throw up exceptions. Diffs ----- metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java 487d292 Diff: https://reviews.apache.org/r/22191/diff/ Testing ------- done Thanks, XIAOBING ZHOU
