Subject solution for java.nio.channels.CancelledKeyException
Date Thu, 30 Oct 2014 16:11:35 GMT
Hello

I am sending this to the mailing list in case other people in the future
have this problem

I had been seeing this error:

java.nio.channels.CancelledKeyException
   at gnu.java.nio.SelectionKeyImpl.readyOps(libgcj.so.10)
   at
org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:187)
   at java.lang.Thread.run(libgcj.so.10)


and it was causing writes to be slow

After some digging I found it was because I was using an outdated version
of java: upgrading from 1.5 to 1.7 fixed this
