----------------------------------
Summary: Bit-Client thread finds closed allocator in
TestDrillbitResilience unit test
Key: DRILL-5156
URL: https://issues.apache.org/jira/browse/DRILL-5156
Project: Apache Drill
Issue Type: Bug
Reporter: Paul Rogers
Priority: Minor
RPC thread attempts to access a closed allocator during the
{{TestDrillbitResilience}} unit test.
Set a Java exception breakpoint for {{IllegalStateException}}. 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.
