I have a wired problem and have searched everywhere and can't seem to get an answer. I am running cloudera 4.6 on a single node and am using local mysql db for hive metastore database. I have many hive tables with data inside that I'm able to query using Apache HUE Hive UI. I can also run queries from command line intermittently getting a
FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
about half the time. When ever I try to pass .hql to hive like below I will get above error everytime.
hive -f test.hql
I also see this error whenever I interact with HIVE via an oozie workflow. I originally had a postgresql local metastore db that was having similar errors.
Below is my hive-site.xml. Any help to get rid of this error would be greatly appreciated.
