Re: How to parse data stored in child node of ZK /hbase/region-in-transition

[Nand kishor Bansal]

Hi,

Using the above clue I researched further to found out that I need to first
use org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper.removeMetaData(byte[]
data) to remove the metadata and then org.apache.hadoop.hbase.
RegionTransition.parseFrom(byte[] data)

Regards,
Nand

Re: How to parse data stored in child node of ZK /hbase/region-in-transition

Hi,

HBase parses the binary data in region-in-transition ZooKeeper node with
org.apache.hadoop.hbase.RegionTransition.parseFrom(byte[] data). It is in
the hbase-client jar. These APIs are private, so use them carefully.

Best regards,
Balazs

Hi

We posted the same in stacker flow.

https://stackoverflow.com/q/50378236/785523

We didn't get any reply there also. Anyone any thoughts?
