List of rootLookups() Examples

Examples of rootLookups()

org.hbase.async.ClientStats.rootLookups()
Returns how many lookups in {@code -ROOT-} were performed.
This number should remain low. It will be 1 after the first access to HBase, and will increase by 1 each time the {@code .META.} region movesto another server, which should seldom happen.
This isn't to be confused with the number of times we looked up where the {@code -ROOT-} region itself is located. This happens even morerarely and a message is logged at the INFO whenever it does.
