ASF GitHub Bot commented on DRILL-5156: --------------------------------------- GitHub user paul-rogers opened a pull request: https://github.com/apache/drill/pull/709 DRILL-5156: BootStrapContext should close threads The Bit-Client thread (that's the thread name) finds a closed allocator in TestDrillbitResilience unit test. This fix (along with DRILL-5157) eliminates two run-time problems seen in this unit tests. BootStrapContext creates two thread pools, but does not close them. This allows the code running in the threads to attempt to access their allocators after the allocator is closed. This fix ensures that the thread pools are closed to avoid the issue.

Run the > {{TestDrillbitResilience}} unit tests. > You will see quite a few exceptions, including the following in a thread > called BitClient-1: > {code} > RootAllocator(BaseAllocator).assertOpen() line 109 > RootAllocator(BaseAllocator).buffer(int) line 191 > DrillByteBufAllocator.buffer(int) line 49 > DrillByteBufAllocator.ioBuffer(int) line 64 > AdaptiveRecvByteBufAllocatpr$HandleImpl.allocate(ByteBufAllocator) line 104 > NioSocketChannel$NioSocketChannelUnsafe(...).read() line 117 > ... > NioEventLoop.run() line 354 > {code} > The test continues (then fails for some other reason), which is why this is > marked as minor. Still, it seems odd that the client thread should attempt to > access a closed allocator. > At this point, it is not clear how we got into this state. The test itself is > waiting for a response from the server in the {{tailsAfterMSorterSorting}} > test. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
