Andrew Kyle Purtell commented on HBASE-27048: --------------------------------------------- Reopening for now but I believe we can re-resolve this after HBASE-27205 . > Server side scanner time limit should account for time in queue > --------------------------------------------------------------- > > Key: HBASE-27048 > URL: https://issues.apache.org/jira/browse/HBASE-27048 > Project: HBase > Issue Type: Improvement > Reporter: Bryan Beaudreault > Assignee: Bryan Beaudreault > Priority: Major > Fix For: 2.5.0, 3.0.0-alpha-4, 2.4.14 > > > When a scan request comes in with a timeout specified and heartbeats/partials > allowed, we calculate a time limit for running the scan to be half of that > timeout. The idea is to return before the timeout expires. > The calculation of that time limit is "now + timeout / 2", where now is the > point at which the scan is starting to run. What's missed here is the scan > may have spent upwards of a few seconds in the IPC queue before being > serviced. In this case, the time limit may extend beyond the timeout of the > request and the server will not return in time. > We should calculate the time limit from ServerCall.getReceiveTime instead to > avoid these timeouts. -- This message was sent by Atlassian Jira (v8.20.10#820010)
