Lars Hofhansl updated HBASE-7578:

This is easily reproducible locally when running the test in a loop.
Here's a jstack when this happened. The interesting part is this (I think):
{code}
"Thread-3" prio=10 tid=0x00007fc6386e5800 nid=0x62f in Object.wait() [0x00007fc62c364000]
   java.lang.Thread.State: WAITING (on object monitor)
        at java.lang.Object.wait(Native Method)
        - waiting on <0x00000007d8fd0ad8> (a java.util.concurrent.atomic.AtomicBoolean)
        at org.apache.hadoop.hbase.catalog.CatalogTracker.waitForMeta(CatalogTracker.java:487)
        - locked <0x00000007d8fd0ad8> (a java.util.concurrent.atomic.AtomicBoolean)
        at org.apache.hadoop.hbase.catalog.CatalogTracker.waitForMetaServerConnectionDefault(CatalogTracker.java:524)
        at org.apache.hadoop.hbase.catalog.TestCatalogTracker$3.run(TestCatalogTracker.java:216)
{code}

So it's waiting for ROOT.
