Optimize mountable HDFS
You can consider certain recommendations to optimize the mountable HDFS.
- Cloudera recommends that you use the
-obig_writesoption on kernels later than 2.6.26. This option allows for better performance of writes.
- By default, the CDH package installation creates the
/etc/default/hadoop-fusefile with a maximum heap size of 128 MB. You might need to change the JVM minimum and maximum heap size for better performance. For example:
export LIBHDFS_OPTS="-Xms64m -Xmx256m"
Be careful not to set the minimum to a higher value than the maximum.
