Xu Cang commented on HBASE-21848:
---------------------------------
I identified this test failure is also caused by
https://issues.apache.org/jira/browse/HBASE-21775
{code:java}
- if (tableName == null &&
ClientExceptionsUtil.isMetaClearingException(regionException)) {
+ if (ClientExceptionsUtil.isMetaClearingException(regionException)) {
// For multi-actions, we don't have a table name, but we want to make
sure to clear the
// cache in case there were location-related exceptions. We don't to
clear the cache
// for every possible exception that comes through, however.
connection.clearCaches(server);
}
{code}
This is causing clearing caches.
