Lars Francke updated HBASE-13599: --------------------------------- Attachment: HBASE-13599-v1.patch Attached a patch that combines those two examples into one to make it easier to copy & paste it. > The Example Provided in Section 69: Examples of the Documentation Does Not > Compile > ---------------------------------------------------------------------------------- > > Key: HBASE-13599 > URL: https://issues.apache.org/jira/browse/HBASE-13599 > Project: HBase > Issue Type: Bug > Components: documentation > Affects Versions: 1.0.0 > Reporter: David Newcomer > Assignee: Lars Francke > Priority: Minor > Attachments: HBASE-13599-v1.patch > > > I'm trying to build and run the example java code I found in the HBase > Documentation, and I'm running into several issues. > 1. I don't have the code/library used in the following import: > import static com.example.hbase.Constants.*; > I don't believe it is included in any of the HBase libraries or documentation. > 2. All of the methods in createOrOverwrite() that use table.getName() should > instead be using table.getTableName() > 3. The interface org.apache.hadoop.hbase.client.Admin is abstract, and can't > be instantiated with a Configuration. Constructing an > org.apache.hadoop.hbase.client.HBaseAdmin would allow the code to compile, > but that constructor is deprecated. > 4. I have no references to the field "TABLE_NAME" or "CF_DEFAULT". I'm > assuming they are Strings in com.example.hbase.Constants. Perhaps those > variables should simply be copied into the the Example? > Link to the documentation section: > http://hbase.apache.org/book.html#_examples > <code> > package com.example.hbase.admin; > import java.io.IOException; > import org.apache.hadoop.hbase.HBaseConfiguration; > import org.apache.hadoop.hbase.HColumnDescriptor; > import org.apache.hadoop.hbase.HTableDescriptor; > import org.apache.hadoop.hbase.TableName; > import org.apache.hadoop.hbase.client.Admin; > import org.apache.hadoop.hbase.io.compress.Compression.Algorithm; > import org.apache.hadoop.conf.Configuration; > import static com.example.hbase.Constants.*; > public class CreateSchema { > public static void createOrOverwrite(Admin admin, HTableDescriptor table) > throws IOException { > if (admin.tableExists(table.getName())) { > admin.disableTable(table.getName()); > admin.deleteTable(table.getName()); > } > admin.createTable(table); > } > public static void createSchemaTables (Configuration config) { > try { > final Admin admin = new Admin(config); > HTableDescriptor table = new > HTableDescriptor(TableName.valueOf(TABLE_NAME)); > table.addFamily(new > HColumnDescriptor(CF_DEFAULT).setCompressionType(Algorithm.SNAPPY)); > System.out.print("Creating table. "); > createOrOverwrite(admin, table); > System.out.println(" Done."); > admin.close(); > } catch (Exception e) { > e.printStackTrace(); > System.exit(-1); > } > } > } > </code> -- This message was sent by Atlassian JIRA (v6.3.4#6332)
