[jira] [Updated] (HADOOP-16925) MetricsConfig incorrectly loads the
configuration whose value is String list in the properties file
[ https://issues.apache.org/jira/browse/HADOOP-16925?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jiayi Liu updated HADOOP-16925:
-------------------------------
Description:
[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".
