Installing HBase apart from cloudera

Question

We have a cluster of 15 nodes with cloudera 5.5.2 installed which comes with HBase version 1.0.0 (Version detail) but we need 1.1.3 as there are some issues with 1.0.0 so we need to install HBase 1.1.3 and keeping all the other services of cloudera as it is.

My Question

Is there a way to install HBase version apart from cloudera.

I tried installing Apache HBase on some other folder with different user but got an issue:

I have already removed HBase from cloudera and no HBase service are running on the cluster but it is still loading the jars of HBase 1.0.0.

it worked after removing the jars of cloudera from node and renamed the folder of hbase — Vikas Hardia

Unfortunately, it is not possible to do this. There are just too many dependencies between HBase and other Hadoop services, like Zookeeper, HDFS, and YARN.

I can only advise you to upgrade the cluster to the desired version
