Jiayi Liu updated HADOOP-16925:
-------------------------------
Environment: (was:
[HADOOP-15549|https://jira.apache.org/jira/browse/HADOOP-15549]modified
loadFirst function in MetricsConfig, and forget to set the DelimiterHandler,
which caused that when loading the properties file, if the configured value is
a String List, the value will not be loaded as a String Array, but just a
String. For example, if we set
{code:java}
*.sink.ganglia.dmax=jvm.metrics.threadsBlocked=70,jvm.metrics.memHeapUsedM=40
{code}
in hadoop-metrics2.properties. If we use
conf.getStringArray("*.sink.ganglia.dmax") to get the value list, we will get
an array with single element, the content of which is
"jvm.metrics.threadsBlocked=70,jvm.metrics.memHeapUsedM=40", which wil cause an
error during loadGangliaConf. loadGangliaConf will assume that the value of
jvm.metrics.threadsBlocked is 70, jvm.metrics.memHeapUsedM, which will cause an
error "java.lang.NumberFormatException: For input string:
"70,jvm.metrics.memHeapUsedM".
