HBase bible (book) have answers on *almost* all questions (1GB default heap is too low for many applications - that is why you see OOME). HBase book: http://hbase.apache.org/book.html
+1 on version upgrade. Is there any particular reason for so old version of HBase? The current is 0.94.12.

Thanks Jean! But the problem is I am using a crawler "Apache Nutch" that supports a HBase version 0.90.6 so I have no option than to restrict to 0.90.6 version. :( I am also getting an out of memory error: heap space while using HBase. I am using default 1GB heap setting in hbase-en.sh. I have 6GB RAM. Please advise. I have set - *hbase.client.scanner.caching* to 1. * hbase.client.scanner.timeout.period *to* 120000 hbase.regionserver.handler.count* to 10. * hbase.rpc.timeout *to 900000 *hbase.regionserver.lease.period* to 900000 *hbase.client.write.buffer* to 2097152 Please advise what can be done to avoid out of memory error: heap space.
