And i have found two record in metastore table VERSION. after reading source
code, i found following code maybe cause the problem:
In the org.apache.hadoop.hive.metastore.ObjectStore.java:6289
String schemaVer = getMetaStoreSchemaVersion();
if (schemaVer == null) {
// metastore has no schema version information
if (strictValidation) {
throw new MetaException("Version information not found in
metastore. ");
} else {
LOG.warn("Version information not found in metastore. "
+ HiveConf.ConfVars.METASTORE_SCHEMA_VERIFICATION.toString() +
" is not enabled so recording the schema version " +
MetaStoreSchemaInfo.getHiveSchemaVersion());
setMetaStoreSchemaVersion(MetaStoreSchemaInfo.getHiveSchemaVersion(),
"Set by MetaStore");
}
}
If there is exception in the getMetaStoreSchemaVersion(), Hive will insert a
duplication record
And i also found my another exception maybe the same cause as above.the
exception is :
