Sankar Hariappan updated HIVE-21206:
------------------------------------
Description:
Hive bootstrap replication of 1TB data onprem to onprem in Hive3 is running
slower compared to Hive2.
Time taken for replications are as below:
|| Hive2- Hive2 || Hive3 - Hive3 ||
|Bootstrap: 01h27m| BootStrap: 03h45m |
Every MoveTask is closing and opening new metastore connection which is causing
slow down.

Time taken for replications are as below:
