--------------------------------------
Summary: Support configuration override for remote cluster of
HFileOutputFormat locality sensitive
Key: HBASE-26196
URL: https://issues.apache.org/jira/browse/HBASE-26196
Project: HBase
Issue Type: Bug
Components: mapreduce
Affects Versions: 2.4.5, 1.8.0, 3.0.0-alpha-2
Reporter: Shinya Yoshida
Assignee: Shinya Yoshida
We introduced support to generate hfile with good locality for a remote cluster
even in HBASE-25608.
I realized we need to override other configurations for the remote cluster in
addition to the zookeeper cluster key.
For example, read from a non-secure cluster and write hfiles for a secure
cluster.
In this case, we use TableInputFormat for non-secure cluster with
hbase.security.authentication=simple in job configuration.
So HFileOutputFormat failed to connect to remote secure cluster because
requires hbase.security.authentication=kerberos in job conf.
Another example is to read from a secure cluster (A) and write hfiles for
another secure cluster (B) and we use different principal for each cluster.
For instance, we use cluster-a/[email protected] for A and
cluster-b/[email protected] for B.
Then we need to override MASTER_KRB_PRINCIPAL and REGIONSERVER_KRB_PRINCIPAL
using cluster-b/[email protected] to connect cluster B.
Thus let's introduce configuration override for remote-cluster-aware
HFileOutputFormat locality-sensitive feature.
