Ok, I am using the quick start VM version 5.2.0. THis iscludes Hue, Hive, Sqoop, and other tools. I have not changed any configuration files.   When I run Hive queries in the Hive editor, they run fine. Also when I execute this Hive SQL command: show tables; It runs fine, the tables it shows are the same in the left hand column.   Then I create an Oozie workflow with a Hive script. The script contains only one command: show tables; The workflow runs with no problem. The submitter is Cloudera.     Then I use Hue and downlaod all the samples for Oozie and the other parts of the framework. I submit the sample workflow that runs a Hive step. The workflow does not succeed. Here is the error:      ava.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient Here is more detail: 2014-11-20 15:06:06,926 WARN HiveActionExecutor:544 - SERVER[quickstart.cloudera] USER[cloudera] GROUP[-] TOKEN[] APP[Hive] JOB[0000004-141120121239453-oozie-oozi-W] ACTION[0000004-141120121239453-oozie-oozi-W@Hive] Launcher exception: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:346) at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:689) at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:633) at org.apache.oozie.action.hadoop.HiveMain.runHive(HiveMain.java:323) at org.apache.oozie.action.hadoop.HiveMain.run(HiveMain.java:284) at org.apache.oozie.action.hadoop.LauncherMain.run(LauncherMain.java:39) at org.apache.oozie.action.hadoop.HiveMain.main(HiveMain.java:66) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.oozie.action.hadoop.LauncherMapper.map(LauncherMapper.java:227) at org.apache.hadoop.mapred.MapRunner.run(MapRunner.java:54)   Here are the settings for the metastore.

So I access mysql, but I do not know the password for the local instalation of MySQL. Here is what I have tried: [cloudera@quickstart ~]$ mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) [cloudera@quickstart ~]$ mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) [cloudera@quickstart ~]$ mysql -u root ERROR 1045 (28000): Access denied for user  'root'@'localhost' (using password: NO) [cloudera@quickstart ~]$     Should I try to make the MySQL instance accessable to Oozie? What config file is Oozie using? I hear some people changing to a Derby database, but if Hue comes with the Quick Start, it should work with the Quick Start, right? Does the Horton Sandbox have the same problems? ... View more
