Hi, the nodes page failed to show up with this patch(2.9 branch), the error is
shown as below, the nodeTableData is just like below. @Jonathan Hung any idea
about this?
var nodeTableData=[\n[\"\",\"/default-rack\",\"RUNNING\",\"XXX:10025\",\"<a
href='XXX:8042'>XXX:8042</a>\",\"<br title='1544757863778'>Fri Dec 14 11:24:23
+0800 2018\",\"\",\"0\",\"<br title='0'>0 B\",\"<br title='8192'>8
GB\",\"0\",\"8\",\"0\",\"<br title='0'>0 B\",\"0\",\"0\",\"2.9.3-SNAPSHOT\"]\n]
!image-2018-12-14-11-33-54-361.png!
with the given example,
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 ->

PASS,modules.TMP_FULL PASS\r\n" +
"\r\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\"],\r\n" +
"...]";
after StringEscapeUtils.escapeJava,
nodeTableDataEscaped = [\"\",\"/IP\",\"UNHEALTHY\",\"host:8041\",\"<a
href='//host:8042'>host:8042</a>\",\"<br title='1542676028146'>Tue Nov 20
