Siddharth Seth updated TEZ-2855: -------------------------------- Attachment: TEZ-2855.1.txt Patch for master to fix the VM NPE. On the logging changes - that's a bigger problem since we aren't handling RuntimeExceptions - created TEZ-2862 to track this. For exceptions we do handle - the vertex name and id is already logged. [~bikassaha], [~hitesh], [~zjffdu] - please review. > NPE while routing events > ------------------------ > > Key: TEZ-2855 > URL: https://issues.apache.org/jira/browse/TEZ-2855 > Project: Apache Tez > Issue Type: Bug > Affects Versions: 0.5.0 > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Priority: Critical > Attachments: 2855log.gz, TEZ-2855.1.txt > > > Observed while running against 0.8.0-alpha.
