Hbase complete list of columns in column family

Contributor

How do we get the complete list of columns that exist in a column Family?

Let us assume i have 5 columns for personal data column familyand 4 columns are present for professional data column family

create 'emp', 'personal data', ’professional data’

HBase does not explicitly track the qualifiers that exist in each family. You either need to maintain this information yourself (e.g. in another table) or scan the data.

Hi @Josh Elser.

I got the answer by unix command as mentiond below.

Command:-

echo "scan 'emp" | $HBASE_HOME/bin/hbase shell | awk -F'=' '{print $2}' | awk -F ':' '{print $2}'|awk -F ',' '{print $1}'
