Brahma Reddy Battula commented on HADOOP-13234: ----------------------------------------------- Ok..Only difference might {{ServerSocket(0).getLocalPort()}} will give free port (32768-61000 on Linux and 49152-65535 on Windows) and {{getPort{p, retries)}} will retries the range between p and 65535( diff might be retry). So we can close this issue..? and to adress the following which is mentioned by [~xyao], need to increase the retry..? {noformat} java.io.IOException: Port is already in use; giving up after 10 times. at org.apache.hadoop.net.ServerSocketUtil.waitForPort(ServerSocketUtil.java:98) at org.apache.hadoop.hdfs.TestDFSShell.testMoveWithTargetPortEmpty(TestDFSShell.java:809) {noformat} > Get random port by new ServerSocket(0).getLocalPort() in > ServerSocketUtil#getPort > --------------------------------------------------------------------------------- > > Key: HADOOP-13234 > URL: https://issues.apache.org/jira/browse/HADOOP-13234 > Project: Hadoop Common > Issue Type: Bug > Reporter: Brahma Reddy Battula > Assignee: Brahma Reddy Battula > Attachments: HADOOP-13234-002.patch, HADOOP-13234.patch > > > As per [~iwasakims] comment from > [here|https://issues.apache.org/jira/browse/HDFS-10367?focusedCommentId=15275604&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15275604] > we can get available random port by {{new ServerSocket(0).getLocalPort()}} > and it's more portable. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
