Hi Guys,

We recently upgraded CDH5.5.1 to CDH5.7. Hue version installed 3.9.0. After upgrade Hue Impala Query Editior stopped working. Impala is functioning fine via impala-shell.

Following error appears in hue/error.log

[20/May/2016 12:56:52 -0700] api ERROR failed to load the HBase clusters

Any help appreciated.

Thanks,
