Hi all,

After I have built impala 1.0 on CentOS 6.4 I want to start the impalad use

${IMPALA_HOME}/bin/start-impalad.sh -use_statestore=false


but there is an error here :
***************************************************************************
E0518 21:33:22.755887 8977 impala-server.cc:648] Unsupported file system.
Impala only supports DistributedFileSystem but the LocalFileSystem was
found. fs.defaultFS(file:///) might be set incorrectly
E0518 21:33:22.756579 8977 impala-server.cc:650] Impala is aborted due to
improper configurations.
***************************************************************************
what's wrong is this?

    Hi,

    Do you have a HDFS cluster with Hive Metastore up and running? I guess not:
    fs.defaultFS(file:///) might be set incorrectly - Alex

    Hi Alex,

    I used the ${IMPALA_HOME}/bin/start-impalad.sh *-use_statestore=false *
      and Do I need a hive metastore up?

    The statestore is not the metastore:
    http://www.cloudera.com/content/cloudera-content/cloudera-docs/Impala/latest/Installing-and-Using-Impala/ciiu_concepts.html?scroll=topic_intro_statestore_unique_1

    Metastore:
    http://www.cloudera.com/content/cloudera-content/cloudera-docs/Impala/latest/Installing-and-Using-Impala/ciiu_concepts.html?scroll=topic_intro_metastore_unique_1

    The metatore knows the location of blocks in HDFS.

    Thank you a lot Alex. I confused the two concepts and I will have a good
    learn about impala.
