Then I leave the notebook open for a few hours - come back and attempt to re-run the same paragraph and get the error: "object 'hiveContext' not found". The only way to resolve this is by restarting the Spark interpreter. Is this expected behaviour? Is there a timeout on the hiveContext perhaps?</P><P>Any insight much appreciated</P> Tue, 02 Aug 2016 18:41:22 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160921#M36642 mph 2016-08-02T18:41:22Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160922#M36643 <P>..also is there a way in SparkR to check first if the sparkcontext and hivecontexts are running?</P> Tue, 02 Aug 2016 18:57:09 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160922#M36643 mph 2016-08-02T18:57:09Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160923#M36644 <P>Hi <A rel="user" href="https://community.cloudera.com/users/5744/mikeyharding.html" nodeid="5744">@mike harding</A></P><P>What version of Zeppelin are you using?</P> Tue, 02 Aug 2016 22:32:17 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160923#M36644 RyanCicak 2016-08-02T22:32:17Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160924#M36645 <P>Its 0.6.0 &gt; <A href="https://zeppelin.apache.org/download.html" target="_blank">https://zeppelin.apache.org/download.html</A></P> Tue, 02 Aug 2016 22:45:10 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160924#M36645 mph 2016-08-02T22:45:10Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160925#M36646 <P><A rel="user" href="https://community.cloudera.com/users/5744/mikeyharding.html" nodeid="5744">@mike harding</A> -&gt; are you running Zeppelin (within HDP 2.5 Sandbox) or running Zeppelin standalone? </P> Tue, 02 Aug 2016 23:01:40 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160925#M36646 RyanCicak 2016-08-02T23:01:40Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160926#M36647 <P>running on HDP2.4 </P> Wed, 03 Aug 2016 00:05:59 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160926#M36647 mph 2016-08-03T00:05:59Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Does-the-HiveContext-object-expire-in-Zeppelin-after-a/m-p/160927#M36648 <P>Are you using Zeppelin directly with Spark interpreter or with Livy interpreter?</P><P>In Z &gt; Livy &gt; Spark scenario, the Livy session is recycled some time of inactivity.
