hdfshelper

Do you find yourself constantly searching for config options in Apache Hadoop? Then this is for you. Fuzzy find your way to the configuration option you're searching for. By default it pulls the options for the latest version aka current.

It prints out the xml ready to be pasted into the configuration file.

Usage

search all options from hdfs-site.xml on version r3.3.4:

hdfshelper -m hdfs -v r3.3.4

copy the output to clipboard (macOS):

hdfshelper -m core | pbcopy

search the description instead of the name (switch):

hdfshelper -s true

You can select more than one option to print with <TAB>.
