- HadoopのData Nodeのファイルシステムは何が良い?
- HadoopのOSの推奨設定は?
回答
Hadoop Slave node partitions: Hadoop should have its own partitions for Hadoop files and logs. Drives should be partitioned using XFS, or ext4 in that order of preference. Do not use LVM; it adds latency and causes a bottleneck.
つまり、XFSか、EXT4が良い。
