What is the fastest way to check if Hbase table exists? Looking at this api :
http://hbase.apache.org/devapidocs/org/apache/hadoop/hbase/client/HBaseAdmin.html
Which of these is the fastest :
With #4 you get list of all tables and iterate trough it and compare if one of those tables matches your table name.
Or there is another, more smart way ?
Using HBaseAdmin.tableExists only takes about 500ms to check if the table exists. We only have two nodes in our cluster, so it might be dependent on the size of your cluster, but it doesn’t seem unreasonably slow.
