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) at org.apache.cassandra.tools.SSTableImport.main(SSTableImport.java:421) thanks!
