Zheng Wang updated HBASE-24875:
-------------------------------
Description:
The description of unassign in Admin.java shows below, it is not true, in fact,
we just close the region now, also we do not need the force param any more.
{code:java}
/**
* Unassign a region from current hosting regionserver. Region will then be
assigned to a
* regionserver chosen at random. Region could be reassigned back to the same
server. Use {@link
* #move(byte[], ServerName)} if you want to control the region movement.
*
* @param regionName Region to unassign. Will clear any existing RegionPlan if
one found.
* @param force If <code>true</code>, force unassign (Will remove region from
regions-in-transition too if
* present. If results in double assignment use hbck -fix to resolve. To be
used by experts).
* @throws IOException if a remote or network exception occurs
*/
void unassign(byte[] regionName, boolean force)
throws IOException;
{code}
