Optionally, start name node only. [[BR]] {{{bin/hadoop-daemon.sh start namenode}}} [[BR]] This should convert the checkpoint to the new version format. 14. Optionally, run {{{lsr}}} command: [[BR]] {{{bin/hadoop dfs -lsr / > dfs-v-new-lsr-0.log}}} [[BR]] and compare with {{{dfs-v-old-lsr-1.log}}} 15. Start DFS cluster.
