fapifta commented on issue #1596: HDDS-2233 - Remove ByteStringHelper and refactor the code to the place where it used URL: https://github.com/apache/hadoop/pull/1596#issuecomment-538504664 Acceptance test failures seems to be related to an internally examined similar failure in XCeiverClientGrpc, where the relevant stack trace is: Caused by: java.lang.NullPointerException at org.apache.hadoop.hdds.scm.XceiverClientGrpc.sendCommandAsync(XceiverClientGrpc.java:387) at org.apache.hadoop.hdds.scm.XceiverClientGrpc.sendCommandWithRetry(XceiverClientGrpc.java:285) at org.apache.hadoop.hdds.scm.XceiverClientGrpc.sendCommandWithTraceIDAndRetry(XceiverClientGrpc.java:251) at org.apache.hadoop.hdds.scm.XceiverClientGrpc.sendCommand(XceiverClientGrpc.java:234) at org.apache.hadoop.hdds.scm.storage.ContainerProtocolCalls.readChunk(ContainerProtocolCalls.java:245) at org.apache.hadoop.hdds.scm.storage.ChunkInputStream.readChunk(ChunkInputStream.java:335) at org.apache.hadoop.hdds.scm.storage.ChunkInputStream.readChunkFromContainer(ChunkInputStream.java:307) at org.apache.hadoop.hdds.scm.storage.ChunkInputStream.prepareRead(ChunkInputStream.java:249) at org.apache.hadoop.hdds.scm.storage.ChunkInputStream.read(ChunkInputStream.java:144) at org.apache.hadoop.hdds.scm.storage.BlockInputStream.read(BlockInputStream.java:239) at org.apache.hadoop.ozone.client.io.KeyInputStream.read(KeyInputStream.java:171) at org.apache.hadoop.fs.ozone.OzoneFSInputStream.read(OzoneFSInputStream.java:52) at org.apache.hadoop.fs.FSInputStream.read(FSInputStream.java:75) at org.apache.hadoop.fs.FSInputStream.readFully(FSInputStream.java:121) at org.apache.hadoop.fs.FSDataInputStream.readFully(FSDataInputStream.java:112) at org.apache.orc.impl.ReaderImpl.extractFileTail(ReaderImpl.java:555) From the Integration test failures org.apache.hadoop.ozone.client.rpc.TestFailureHandlingByClient failure might be related, but there in the output before the error we can see that the client wanted replication factor of 3, while the cluster had only 1 DN. So issues seem to be unrelated, however I can not run these tests locally as easy as they are timing out in my local machine.
