-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
Did a test on recursive chown on a fedora 9 box here (2xquad core,16Gram) Took about 12.5 minutes to complete for 45000 files. (hmm approx 60 files/sec) This was the namenode that I executed the command on Q1. Is this rate (60 files/sec) typical of what other folks are seeing ? Q2. Are there any dfs/jvm parameters I should look at to see if I can improve this time /home/hadoop/hadoop-0.18.1/bin/hadoop dfs -chown -R frank:frank /home/frank/proj100 real 12m38.631s user 1m54.662s sys 0m33.124s time /home/hadoop/hadoop-0.18.1/bin/hadoop dfs -count /home/frank/proj100 220 45891 3965996260 hdfs://namenode:9000/home/frank/proj100 real 0m1.579s user 0m0.686s sys 0m0.129s cheers / frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjln0MACgkQpZzN+MMic6dqgQCdEtto3qEhKIc50ICMf058w8ar o4QAoILcDRDYmUUuxPwSFh7LNTQdKodn =xuZE -----END PGP SIGNATURE-----
