(Updated Feb. 2, 2017, 5:11 a.m.) Review request for sentry, Alexander Kolbasov, Lei Xu, Hao Hao, kalyan kumar kalvagadda, and Vadim Spector. Changes ------- 1. Simplified setting up KerberosContext as retry logic is not necessarily required as if Kerberos setup fails for the first time, it is unlikely to pass with retries as well (based on approach used in SentryServer.java) 2. SentryKerberosContext to use non-server (client) mode for the reasons: a. Reflects the right behaviour as we are trying to connect to HMS as a client. b. client mode automatically starts up ticket renewal thread (we can use SENTRY-1427 to check the correctness of this logic) Repository: sentry Description ------- SENTRY-1619: Fix the secure HMS connection code in HMSFollower -- HMSFollower has bugs in implementing logic that's preventing secure HMS connection from taking place. 1. Need to use the right principal and keytab to use for the connection. 2. Fix the while blocks to allow the connection setup to happen. Diffs (updated) ----- sentry-provider/sentry-provider-db/src/main/java/org/apache/sentry/service/thrift/HMSFollower.java 749c2ce8f89fe5960af5a4b48ff45a38091350f4 Diff: https://reviews.apache.org/r/56191/diff/ Testing ------- Sentry server log: ```bash 2017-02-01 14:02:48,537 INFO org.apache.sentry.service.thrift.HMSFollower: HMSFollower is being initialized 2017-02-01 14:02:50,545 INFO DataNucleus.Persistence: Property datanucleus.cache.level2 unknown - will be ignored 2017-02-01 14:02:51,911 WARN com.jolbox.bonecp.BoneCPConfig: Max Connections < 1.
