Sometimes conenction is lost between Hive and Hive editor in Hue. the error is the following:
Could not connect to my-server:10000
Currently we are resolving this problem by restarting apache, but it's becoming so frequent.
have you any idea what could be the problem?
Check the HS2 logs . That would indicate why would HS2 be going down when Hue is unable to connect to it.
