Hi to all, running a job that writes parquet-thrift files I had this exception (in a Task Manager):
io.netty.channel.nio.NioEventLoop - Unexpected exception in the selector loop. java.lang.OutOfMemoryError: Java heap space 2016-05-12 18:49:11,302 WARN org.jboss.netty.channel.socket.nio.AbstractNioSelector - Unexpected exception in the selector loop. java.lang.OutOfMemoryError: Java heap space 2016-05-12 18:49:11,302 ERROR org.apache.flink.runtime.io.disk.iomanager.IOManager - The handler of the request-complete-callback threw an exception: Java heap space java.lang.OutOfMemoryError: Java heap space 2016-05-12 18:49:11,303 ERROR org.apache.flink.runtime.io.disk.iomanager.IOManager - I/O reading thread encountered an error: segment has been freed java.lang.IllegalStateException: segment has been freed at org.apache.flink.core.memory.HeapMemorySegment.wrap(HeapMemorySegment.java:85) at org.apache.flink.runtime.io.disk.iomanager.SegmentReadRequest.read(AsynchronousFileIOChannel.java:310) at org.apache.flink.runtime.io.disk.iomanager.IOManagerAsync$ReaderThread.run(IOManagerAsync.java:396) 2016-05-12 18:49:11,303 ERROR org.apache.flink.runtime.io.disk.iomanager.IOManager - I/O reading thread encountered an error: segment has been freed Any idea of what could be the cause?
