I am running dockerized hadoop cdh 4.6.0 with supervisor . I have opened the docker container and tried the following two commands. Got confused a lot. jps 103 -- process information unavailable 291 -- process information unavailable 107 -- process information unavailable 449 JpsI read process info unavail means process is zombie. But i checked the status of these processes using in the same containerroot@1389ca416997:/# /etc/init.d/hadoop-hdfs-namenode status   * Hadoop namenode is runningroot@1389ca416997:/# /etc/init.d/hadoop-hdfs-secondarynamenode status   * Hadoop secondarynamenode is runningroot@1389ca416997:/# /etc/init.d/hadoop-hdfs-datanode status   * Hadoop datanode is runningWhat causes this ambiguity? or Am i wrong?
Does jps lie? If not, what else is this?
process;docker
