Hadoop - Impala Default TException error

Default TException

If you see this error message in your Impala UI (Under "My Queries" nad "History"), probably because you restart hue/impala in wrong order. Since Impala has dependency on Hue but Hue does not have any dependency on Impala, if you restart Hue, Impala might get stuck sometime. To solve this, just stop Impala, Stop Hue, restart Hue then restart Impala.
