Eason Zhang closed TRAFODION-2313. ---------------------------------- > dcscheck doesn't return while invoking by REST call 'dcs/summary' > ----------------------------------------------------------------- > > Key: TRAFODION-2313 > URL: https://issues.apache.org/jira/browse/TRAFODION-2313 > Project: Apache Trafodion > Issue Type: Bug > Components: dcs > Reporter: Eason Zhang > Assignee: Eason Zhang > > When a REST 'get' request 'dcs/summary' is invoked, it will call 'dcscheck' > to get the dcs master info, but in some specific cases, the 'dcscheck' > command will never return a value, so REST server hangs, it cannot receive > any other REST requests any more. > The reason why 'dcscheck' doesn't return is that it calls the zookeeper CLI > using pipe like this: > echo “ls $dcsznode” | $DCS_INSTALL_DIR/bin/dcs zkcli > $dcstmp > Modify it to not using pipe can solve this issue. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
