Subject Re: json2sstable
Date Wed, 13 Apr 2011 09:53:06 GMT
managed to resolve the earlier error
but is getting this exception now, any way to increase the heap space, or is a non-related
issue?

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
	at org.apache.cassandra.io.util.BufferedRandomAccessFile.<init>(BufferedRandomAccessFile.java:123)
	at org.apache.cassandra.io.sstable.SSTableWriter.<init>(SSTableWriter.java:78)
	at org.apache.cassandra.io.sstable.SSTableWriter.<init>(SSTableWriter.java:65)
	at org.apache.cassandra.tools.SSTableImport.importUnsorted(SSTableImport.java:211)
	at org.apache.cassandra.tools.SSTableImport.importJson(SSTableImport.java:197)

thanks!
