# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

This gist includes components of a oozie (trigger file initiated) coordinator job - 
scripts/code, sample data and commands;  Oozie actions covered: hdfs action, email action, 
java main action, hive action;  Oozie controls covered: decision, fork-join; The workflow 
includes a sub-workflow that runs two hive actions concurrently.  The hive table is 
partitioned;  Parsing uses hive-regex serde, and Java-regex.  Also, the java mapper, gets 
the input directory path and includes part of it in the key.
 
Usecase
-------
Parse Syslog generated log files to generate reports;
