Andrew Purtell created HBASE-10607:
--------------------------------------
Summary: [JDK8] NoSuchMethodError involving
ConcurrentHashMap.keySet if running on JRE 7
Key: HBASE-10607
URL: https://issues.apache.org/jira/browse/HBASE-10607
Project: HBase
Issue Type: Task
Reporter: Andrew Purtell
Priority: Trivial
If you try running HBase built with Java 8 on a Java 7 JRE, then processes will
fail early with:
{noformat}
java.lang.NoSuchMethodError:
java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;
{noformat}
I came across this incidentally. I suppose we should consider documenting this
in the manual in the Troubleshooting section.
