https://community.cloudera.com/t5/Support-Questions/Hue-connects-hiveserver2-timeout-in-hortonworks/m-p/148771#M111297 <P>Hi, everybody</P><P>I think i encountered one messy problem. After installing the hadoop，hive，hue, etc. services successfully and using hue without any problem for a while, I encountered such one problem. it printed the timeout error when i tried to login in to the beeswax page. I have tried some ways including installing the hiveserver2 service and hue server service in the same host, changing the value of hive_server_host from fqdn to localhost, changing the server_conn_timeout from 120 to 300 of hue.ini, etc. But all these ways didn't work. I think maybe i should read the source code of hue and hive, and then trace it. Maybe you guys have solutions, do you? Thanks in advance.</P><P>Versions of HDP and hue, hive:</P><P>HDP: 2.5.0.0</P><P>hue: 2.6.1.2.5.0.0</P><P>hive: 1.2.1000</P><P>Parts of the logs of hivesever2 in both cases:</P><P>1. successfully login from hue ui</P><P>see the text file or png file.</P><P><A href="https://community.cloudera.com/legacyfs/online/attachments/13457-success-hiveserver2.txt" target="_blank">success-hiveserver2.txt</A></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="13458-success-hiveserver2.png" style="width: 1568px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/21303i47D14937F6B30593/image-size/medium?v=v2&amp;px=400" role="button" title="13458-success-hiveserver2.png" alt="13458-success-hiveserver2.png" /></span></P><P>2. failed to login from hue ui, or timeout error</P><P>see the text file or png file.</P><P><A href="https://community.cloudera.com/legacyfs/online/attachments/13459-fail-hiveserver2.txt" target="_blank">fail-hiveserver2.txt</A></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="13460-fail-hiveserver2.png" style="width: 1565px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/21304iDD722B9FAC8F509D/image-size/medium?v=v2&amp;px=400" role="button" title="13460-fail-hiveserver2.png" alt="13460-fail-hiveserver2.png" /></span></P><P>Parts of the logs of hue in fail case:</P><P>see the text file.</P><P><A href="https://community.cloudera.com/legacyfs/online/attachments/13461-fail-hue.txt" target="_blank">fail-hue.txt</A></P><P>Please use vim or other editor open the text file because of the aligning problem.
