Nutch with hadoop 2 7 error GC overhead limit exceeded

0 votes

I have a small cluster of 5 systems to crawl few websites from web. Apache nutch 2.3.1 in configured on master. There are 4 workers. Most configuration of hadoop is left default. Each node has total 16 GB memory. While running a job I have observed following error and job was failed.

2019-04-09 23:04:06,732 INFO [main] org.apache.gora.mapreduce.GoraRecordWriter: Flushing the datastore after 5590000 records
2019-04-09 23:07:27,944 ERROR [main] org.apache.hadoop.mapred.YarnChild: Error running child : java.lang.OutOfMemoryError: GC overhead limit exceeded

	at java.util.ArrayList.ensureExplicitCapacity(
	at java.util.ArrayList.ensureCapacityInternal(
	at java.util.ArrayList.add(
	at org.apache.hadoop.hbase.client.MultiAction.add(

Now the question is what and where I should updated heap to get rid of this issue. Is it datanode issue or mapreduce issue.

Seems like there's a problem in applying the changes. Did you try restarting?
Yes, I tried to restart complete cluster. The problem was finished for few days then it appeared again as questioned.
Can you mention what changes you have made to the configuration?

Hi @ Hafiz. I had the same issue a few months ago. The problem was with the -XX parameter. What parameters have you used for this?

Can you please send the configuration file?
