Project: Chukwa
Issue Type: Improvement
Components: User Interface
Environment: Java 6, MacOSX 10.6
Reporter: Eric Yang
Assignee: Eric Yang
Fix For: 0.5.0
When select a column family, the only way to figure out all columns inside the
column family is to do a scan. Since HBase does not have an API to get column
names only, we have to provide a temporary workaround. We can add an option to
do full table scan, and we scan small amount of data to figure out the column
patterns by default. This short cut make assumption that data are in repeated
pattern, scanning one row should be sufficient to find all the columns. The
same principle applies in scanning for unique row names.
