It works fine, however, a small problem is, when i use the hadoop fs -ls command in the terminal to get the list of files in the hdfs, it took much more time(10+ sec) to get the response compared to 2-3 secs before i update the version of hadoop.( get is slow too) Can any one exaplain a little bit of what might cause the problem or some configuration goes wrong? Below is the log: 15/04/08 10:51:18 DEBUG util.Shell: setsid exited with exit code 0 15/04/08 10:51:18 DEBUG conf.Configuration: parsing URL jar:file:/data/dbcenter/cdh5/hadoop-2.5.0-cdh5.2.0/share/hadoop/common/hadoop-common-2.5.0-cdh5.2.0.jar!/core-default.xml 15/04/08 10:51:18 DEBUG conf.Configuration: parsing input stream sun.net.www.protocol.jar.JarURLConnection$JarURLInputStream@57316e85 15/04/08 10:51:18 DEBUG conf.Configuration: parsing URL file:/data/dbcenter/cdh5/hadoop-2.5.0-cdh5.2.0/etc/hadoop/core-site.xml 15/04/08 10:51:18 DEBUG conf.Configuration: parsing input stream java.io.BufferedInputStream@31818dbc 15/04/08 10:51:19 DEBUG lib.MutableMetricsFactory: field org.apache.hadoop.metrics2.lib.MutableRate org.apache.hadoop.security.UserGroupInformation$UgiMetrics.loginSuccess with annotation @org.apache.hadoop.metrics2.annotation.Metric(valueName=Time, value=[Rate of successful kerberos logins and latency (milliseconds)], about=, type=DEFAULT, always=false, sampleName=Ops) 15/04/08 10:51:19 DEBUG lib.MutableMetricsFactory: field org.apache.hadoop.metrics2.lib.MutableRate org.apache.hadoop.security.UserGroupInformation$UgiMetrics.loginFailure with annotation @org.apache.hadoop.metrics2.annotation.Metric(valueName=Time, value=[Rate of failed kerberos logins and latency (milliseconds)], about=, type=DEFAULT, always=false, sampleName=Ops) 15/04/08 10:51:19 DEBUG lib.MutableMetricsFactory: field org.apache.hadoop.metrics2.lib.MutableRate org.apache.hadoop.security.UserGroupInformation$UgiMetrics.getGroups with annotation @org.apache.hadoop.metrics2.annotation.Metric(valueName=Time, value=[GetGroups], about=, type=DEFAULT, always=false, sampleName=Ops) 15/04/08 10:51:19 DEBUG impl.MetricsSystemImpl: UgiMetrics, User and group related metrics 15/04/08 10:51:19 DEBUG security.Groups: Creating new Groups object 15/04/08 10:51:19 DEBUG util.NativeCodeLoader: Trying to load the custom-built native-hadoop library... 15/04/08 10:51:19 DEBUG util.NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError: no hadoop in java.library.path 15/04/08 10:51:19 DEBUG util.NativeCodeLoader: java.library.path=/data/dbcenter/cdh5/hadoop-2.5.0-cdh5.2.0/lib/native 15/04/08 10:51:19 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 15/04/08 10:51:19 DEBUG util.PerformanceAdvisory: Falling back to shell based 15/04/08 10:51:19 DEBUG security.JniBasedUnixGroupsMappingWithFallback: Group mapping impl=org.apache.hadoop.security.ShellBasedUnixGroupsMapping 15/04/08 10:51:19 DEBUG security.Groups: Group mapping impl=org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback;
