Hi Guys,

I tried to run Hbase Shell in my system. I set all the properties properly, but still I got this below error.

+    <programlisting>Caused by: java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;
+  at org.apache.hadoop.hbase.master.ServerManager.findServerWithSameHostnamePortWithLock(ServerManager.java:393)

+  at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2020)

How can I solve this below error?

Hi@akhtar,

I think there is a problem in your jdk version. It is not compatible with Hbase. Check which jdk version is compatible with which Hbase version.
