Arun Mahadevan commented on STORM-1692:
---------------------------------------
HBaseSecurityUtil uses legacyprovider.login(), which finally ends up in
UserGroupInformation.loginUserFromKeytab() which modifies the static loginUser
(currently logged in user) and this is causing issues if two tasks in the same
jvm login with different credentials.
The entire login method should rather be re-written to not affect the current
user during login.
> org.apache.storm.hbase.security.HBaseSecurityUtil#login uses broken double
> checked locking.
