Guangxu Cheng updated HBASE-18880: ---------------------------------- Attachment: hbase-hbase-rest-locolhost.out jstack-5750.log hbase-hbase-rest-locolhost.log > Failed to start rest server if the value of hbase.rest.threads.max is too > small. > -------------------------------------------------------------------------------- > > Key: HBASE-18880 > URL: https://issues.apache.org/jira/browse/HBASE-18880 > Project: HBase > Issue Type: Bug > Components: REST > Affects Versions: 3.0.0, 2.0.0-alpha-4 > Reporter: Guangxu Cheng > Assignee: Guangxu Cheng > Priority: Critical > Fix For: 2.0.0-beta-1 > > Attachments: HBASE-18880.master.v0.patch, > hbase-hbase-rest-locolhost.log, hbase-hbase-rest-locolhost.out, > jstack-5750.log > > > After HBASE-18224, Jetty has be updated to 9.4.6, and it requires more > threads to start up. > If the value of hbase.rest.threads.max is too small, the rest server will > fail to start. > What I observed was as follows: > 1. The process did not exit. (At the beginning, I thought the rest server has > been start normally because of the process exists.) > 2. Can't connect to the rest server and I didn't found any exception log in > ***.log. > 3. the main thread has exited (jstack log). > 4. Found the exception information from ***.out. > {code} > java.lang.IllegalStateException: Insufficient threads: max=5 < > needed(acceptors=1 + selectors=8 + request=1) > at org.eclipse.jetty.server.Server.doStart(Server.java:414) > at > org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:68) > at org.apache.hadoop.hbase.rest.RESTServer.main(RESTServer.java:360) > {code} > I think the process should exit and log the information in ***.log when it > happens. > So that the user can directly discover that the rest server is abnormal. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
