Hi all, We have a Kerberized Accumulo 1.7.0 (HDP3) cluster with 25 tservers. Recently, a couple of clients were reporting errrors writing data (fat fingered from cluster, apologies for typos):
org.apache.accumulo.core.client.impl.TabletServerBatchWriter.checkForFailures ... Caused by: org.apache.accumulo.core.client.impl.TabletServerBatchWriter$MutationWriter.sendMutationsToTabletServer Digging into the logs on the problematic tservers, I think the following was firing, but don't know why: https://github.com/apache/thrift/blob/0.9.1/lib/java/src/org/apache/thrift/transport/TIOStreamTransport.java#L132 Also, the tserver logs report: Internal error processing closeUpdate....TException: Commits are held For now, I have stopped the two problematic tservers but any help debugging would be much appreciated. James
