---------------------------------
Summary: Occasional inaccurate timeout time calculation with
System.nanotime in batch read buffer pool
Key: FLINK-31396
URL: https://issues.apache.org/jira/browse/FLINK-31396
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Reporter: Yuxin Tan
When running TPC-DS tests, I encountered the read buffer request timeout
because of configuring too less read buffers. But I found the timeout time may
be less than 5m occasionally, 5m is the expected time.
I read the docs of System.nanotime, the docs say that t1 < t0 should not be
used, because of the possibility of numerical overflow. I tested the
System.currentTimeMillis and it can work as expected.
