----------------------------------------------
Summary: HS2 HTTP server hangs on large chunked requests
Key: IMPALA-9383
URL: https://issues.apache.org/jira/browse/IMPALA-9383
Project: IMPALA
Issue Type: Bug
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
There's a bug in THttpTransport that causes it to hang when sent a large,
chunked request.
The issue is that in each call to THttpTransport::read(), it always starts by
calling refill() which reads more data off the socket, but for chunked requests
each call to read() only processes a single chunk.
So, if more than one chunk is read off the socket at a time, you can end up
with more chunks still needing to be processed but no more data to read off the
socket, and the next call to THttpTransport::read() will hang when it calls
refill().
