Christopher Tubbs commented on ACCUMULO-4415: --------------------------------------------- It would be difficult to use it before Accumulo was initialized, and then later, it'd just be annoying for Hadoop to discover the (current) instance ID to use. > Tracer requires instance.secret > ------------------------------- > > Key: ACCUMULO-4415 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4415 > Project: Accumulo > Issue Type: Bug > Components: trace > Reporter: Christopher Tubbs > Fix For: 1.8.1 > > > Tracer incorrectly uses instance.secret for its /tracers area in ZooKeeper. > The tracer does not use the Accumulo system credentials, and instead uses a > specific tracer username and password. It should also not use the > instance.secret (which is for the system credentials). > A side effect of this bug is that ChangeSecret does not update the /tracers > ACLs in ZooKeeper, preventing the tracer from working entirely after the > instance.secret is changed. > The following error will be seen in the monitor after the ChangeSecret tool > is run. > {code} > Thread 'tracer' died. > org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = > NoAuth for /tracers/trace- > at > org.apache.zookeeper.KeeperException.create(KeeperException.java:113) > at > org.apache.zookeeper.KeeperException.create(KeeperException.java:51) > at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:783) > at > org.apache.accumulo.fate.zookeeper.ZooUtil.putEphemeralSequential(ZooUtil.java:464) > at > org.apache.accumulo.fate.zookeeper.ZooReaderWriter.putEphemeralSequential(ZooReaderWriter.java:99) > at > org.apache.accumulo.tracer.TraceServer.registerInZooKeeper(TraceServer.java:318) > at > org.apache.accumulo.tracer.TraceServer.<init>(TraceServer.java:255) > at > org.apache.accumulo.tracer.TraceServer.main(TraceServer.java:360) > at > org.apache.accumulo.tracer.TracerExecutable.execute(TracerExecutable.java:33) > at org.apache.accumulo.start.Main$1.run(Main.java:120) > at java.lang.Thread.run(Thread.java:745) > {code} > This affects at least the current 1.8 branch (1.8.0-SNAPSHOT), but I haven't > checked earlier versions. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
