[ https://issues.apache.org/jira/browse/YARN-9036?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16692514#comment-16692514 ]
Keqiu Hu commented on YARN-9036:
--------------------------------
Before the change, there is an invalid new line in the generated Javascript:
{code:java}
var nodeTableData=[
["","/IP","UNHEALTHY","host:8041","<a href='//host:8042'>host:8042</a>","<br title='1542676028146'>Tue Nov 20 01:07:08 +0000 2018","ERROR -> /dev/sdb - modules.DISK FAILED | OK -> User:yarn,modules.CPU PASS,modules.RAM PASS,modules.PROCESSES PASS,modules.NET PASS,modules.TMP_FULL PASS
;1/2 local-dirs have errors: [ /tmp/yarn : Directory is not writable: /tmp/yarn ] 1/2 log-dirs have errors: [ /tmp/userlogs : Directory is not writable: /tmp/userlogs ] ","0","<br title='0'>0 B","<br title='0'>0 B","0","0","2.9.0.48"],
...]
{code}
After the change:
{code:java}
var nodeTableData=[
["","/IP","UNHEALTHY","host:8041","<a href='//host:8042'>host:8042</a>","<br title='1542676028146'>Tue Nov 20 01:07:08 +0000 2018","ERROR -> /dev/sdb - modules.DISK FAILED | OK -> User:yarn,modules.CPU PASS,modules.RAM PASS,modules.PROCESSES PASS,modules.NET PASS,modules.TMP_FULL PASS\n;1/2 local-dirs have errors: [ /tmp/yarn : Directory is not writable: /tmp/yarn ] 1/2 log-dirs have errors: [ /tmp/userlogs : Directory is not writable: /tmp/userlogs ] ","0","<br title='0'>0 B","<br title='0'>0 B","0","0","2.9.0.48"],{code}
