Step 2: Configure Hue for HPE Ezmeral Data Fabric Database

About this task

To configure Hue for HPE Ezmeral Data Fabric Database, edit the hbase section of the hue.ini file, which looks like this:

[hbase]
  # Comma-separated list of HBase Thrift servers for
  # clusters in the format of '(name|host:port)'.
  ## hbase_clusters=(Cluster|localhost:9090)

  # Hard limit of rows or columns per row fetched before truncating.
  ## truncate_limit = 500

In this file, make the following changes:

Procedure

Uncomment the ## hbase_clusters=(Cluster|localhost:9090) statement and provide the list of HBase Thrift servers.
```
hbase_clusters=(<clustername1>|<hostname1>:9090),(<clustername2>|<hostname2>:9090)[,...]
```
Uncomment the truncate_limit statement and change the value if necessary.
