Examples of org.apache.hadoop.hbase.client.Admin.enableTable()

org.apache.hadoop.hbase.client.Admin.enableTable()
Enable a table. May timeout. Use {@link #enableTableAsync(org.apache.hadoop.hbase.TableName)}and {@link #isTableEnabled(org.apache.hadoop.hbase.TableName)} instead. The table has to be indisabled state for it to be enabled. @param tableName name of the table @throws IOException if a remote or network exception occurs There could be couple types ofIOException TableNotFoundException means the table doesn't exist. TableNotDisabledException means the table isn't in disabled state. @see #isTableEnabled(org.apache.hadoop.hbase.TableName) @see #disableTable(org.apache.hadoop.hbase.TableName) @see #enableTableAsync(org.apache.hadoop.hbase.TableName)
