--------------------------------------
Summary: listSplits fails on IBM JVM
Key: ACCUMULO-4040
URL: https://issues.apache.org/jira/browse/ACCUMULO-4040
Project: Accumulo
Issue Type: Sub-task
Components: client
Environment: IBM J9 JVM. Accumulo 1.6
Reporter: Jared Winick
I saw a user running on the IBM J9 JVM and the TableOperationsImpl.listSplits
never returns as it gets stuck in a loop throwing exceptions. It appears like
the root cause is that listSplits calls
TableMetadataServicer.getTabletLocations which then calls validateEntries. In
here it attempts to cast a Set to a SortedSet
{code:java}
SortedSet<KeyExtent> tabletsKeys = (SortedSet<KeyExtent>) tablets.keySet();
{code}
Looks like you can get away with this on a Oracle/OpenJDK JVM as tablets is a
TreeMap and its impl returns a NavigableSet which is a SortedSet.
