I am try to pump some data into Accumulo but I keep encountering Exception in thread "Thrift Connection Pool Checker" java.lang.OutOfMemoryError: Java heap space
at java.util.HashMap.newValueIterator(HashMap.java:971) at java.util.HashMap$Values.iterator(HashMap.java:1038) at org.apache.accumulo.core.client.impl.ThriftTransportPool$Closer.closeConnections(ThriftTransportPool.java:103) at org.apache.accumulo.core.client.impl.ThriftTransportPool$Closer.run(ThriftTransportPool.java:147) at java.lang.Thread.run(Thread.java:745) I tried, as a work around, creating a new BatchWriter and closing the old one every ten thousand rows, but to no avail. Data gets written up to the 200kth row, then the error. I have a table of 8M rows in a RDB that I am pumping into Acc via a groovy script. The rows are narrow, a short text field and four floats. I googled of course but nothing was helpful. What can be done? Thanks so much. -- There are ways and there are ways, Geoffry Roberts
