When I use The Web UI for HBase in hue，I just get an error message: API Error: None, and the log says：

PopupException: Api Error: None

and config in hue.ini is

[hbase]
hbase_clusters=(Cluster|ip-172-31-13-29.cn-north-1.compute.internal:9290)

and thrift port is 9290 (hbase.regionserver.thrift.port), Enable HBase Thrift Server Framed Transport is false (hbase.regionserver.thrift.framed)

Are you using Thrift Server v1 (and not v2)?

Did you make sure that 'framed' was also selected in the hue.ini?

[hbase]
thrift_transport=framed

HBASE VERSION 1.4.6
HUE VERSION 4.2.0

I am running clustered HBASE on AWS EMR

To fix the issue

1) Start thrift1 on master node of HBASE. Default port is 9090 or make sure its running

./bin/hbase-daemon.sh start thrift -p PORT_NUMBER

2) Change hui.ini or pseudo-distributed.ini configuration settings

[hbase]

  hbase_clusters=(Cluster|MASTER_IP_OR_STANDALONE_IP:9090)

  # Copy these files from where hbase is installed in case of distributed hbase. 
  # Like hbase-site.xml , hbase-policy.xml and regionalservers file
  hbase_conf_dir=PATH_OF_HBASE_CONFIG_FILES

  # 'buffered' used to be the default of the HBase Thrift Server.
  thrift_transport=buffered

3) Restart the hue server
