@bleonhardi, How can I connect to Hive with a UNIX/HDFS user? Let's say I have a user named "newuser". I tried the following, but apparently I am doing something wrong. % su - newuser % beeline beeline> !connect -n newuser -p jdbc:mysql://my.host.com/hive

Same issue with Hive action. It is frustrating and inefficient that such a common use case cannot be accommodated.

@Saurabh I have resolved this kind of error for multiple customers by following below steps: #Command 1: hadoop fs -put /usr/hdp/current/atlas-server/hook/hive/* hdfs://<NN>/user/oozie/share/lib/lib_<Timestamp>/hive/ #Command 2(Please run below command on Oozie server as 'oozie' user): oozie admin -oozie http://<oozie-server:11000/oozie -sharelibupdate Re-run your Oozie workflow, It should succeed without any issue. Hope this helps! Note - Update Oozie sharelib part is missing in the stackoverflow's answer.

Not really. You mean as a persisted storage layer under hibernate and ejbs correct? Hive wouldn't work well for this since it's not an oltp database. It is a wareshoue.. So that would leave hbase most likely with Apache Phoenix. I Googled it a bit and focused on hibernate because that seems to be the most popular recently and did not find a connector for Phoenix. Doesn't mean it's not possible to write one. Googled a bit more and there is Hibernate OGM for NoSQL stores as well. Unfortunately it currently does not support HBase. http://hibernate.org/ogm/ So the two possibilities would be to write an extension for OGM for HBase or rewrite a connector for Apache Phoenix. I wrote one for Netezza a while back and it should not be terribly difficult, although the Phoenix syntax has some differences to standard SQL ( UPSERT instead of INSERT ... )

You should be able to see the query in the HiveServer log or a Hive-related UI, like Hive View for Ambari or Hue (there should be a query history). The Resourcemanager does not show the full query, because the job is only named after a partial of the query. Why only a partial? Some queries can be quite large and Job Name is limited in regards to the allowed #characters.

Iif you put this machine in a separate config group and remove referencw to the directories used you can keep the machine up. Removing disk and not replacing will mean your data will be writing to OS filesystem. Also do what Benjamin siggests and increase tolerance.
