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 Traceback (most recent call last): File "/usr/lib/hue/apps/hbase/src/hbase/api.py", line 64, in getClusters full_config = json.loads(conf.HBASE_CLUSTERS.get().replace("'", "\"")) File "/usr/lib64/python2.6/json/__init__.py", line 307, in loads return _default_decoder.decode(s) File "/usr/lib64/python2.6/json/decoder.py", line 319, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib64/python2.6/json/decoder.py", line 338, in raw_decode raise ValueError("No JSON object could be decoded") ValueError: No JSON object could be decoded [20/May/2016 12:56:54 -0700] conf ERROR No available Impalad to send queries to.
