Hi I am using HBase 0.90.6 - cdh3u4. I am inserting data into the HBase table almost every second using my Java code. After running the program for 3-4 days, I am getting heap space error while running Hbase on certain nodes of my cluster. I have allocated 2G as the heapspace of Hbase. I can't increase the Heapspace allocated to Hbase, is there some way in which I can prevent this from happening programmatically or through any particular configuration?
The following is the log: serverName=server1,60020,1340693606454, load=(requests=4, regions=18, usedHeap=1972, maxHeap=1993): OutOfMemoryError, aborting java.lang.OutOfMemoryError: Java heap space at java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:57) at java.nio.ByteBuffer.allocate(ByteBuffer.java:329) at org.apache.hadoop.hbase.ipc.ByteBufferOutputStream.<init>(ByteBufferOutputStream.java:44) at org.apache.hadoop.hbase.ipc.ByteBufferOutputStream.<init>(ByteBufferOutputStream.java:37) at org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:1064) Thanks Prakrati -----Original Message----- From: Asaf Mesika [mailto:[email protected]] Sent: Thursday, June 28, 2012 10:26 PM To: [email protected] Subject: Re: Out of memory error in Hbase How Manu puts object are sending to the server? Maybe you should decrease this amount?
