-------------------------------------------
Hi [~zghaobac] ,
I added a condition in doCommandLine to check for this.
User should provide all four peer snapshot related params or none.
If user misses any one then we throw validation error saying all peer snapshot
related parameters need to be provided.
Below condition.
+ if (peerSnapshotName != null || peerSnapshotTmpDir != null ||
peerFSAddress != null
+ || peerHBaseRootAddress != null) {
+ if (peerSnapshotName == null || peerSnapshotTmpDir == null ||
peerFSAddress == null
+ || peerHBaseRootAddress == null) {
+ printUsage(
+ "Peer snapshot name, peer snapshot temp location, Peer HBase root
address and "
+ + "peer FSAddress should be provided to use snapshots in peer
cluster");
+ return false;
+ }
+ }

> As of now VerifyReplicatin tool is running using normal HBase scanners. If
> you want to run VerifyReplication multiple times on a production live
> cluster with large tables then it creates extra load on HBase layer. So if we
> implement snapshot based support then both in source and target we can read
> data from snapshots which reduces load on HBase
