Hi,
I have created a snapshot of the hbase table and clone it but when I am trying to export to another cluster I am getting connection refused.
I am not running the below command as a hbase user . How can I change to hbase user and will that help in this command execution?
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot tbl_snapshot -copy-to hdfs://<cluster2>:8020/hbase -mappers 16
Error:
Exception in thread "main" java.net.ConnectException: Call From cluster1 to cluster2:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
