                                             throws java.io.IOException

Create an HFile with the given number of rows between a given start key and end key @ family:qualifier. The value will be the key value. This file will use certain data block encoding algorithm.

Throws:

java.io.IOException

createHFileWithTags

public static void createHFileWithTags(Configuration configuration,
                                       FileSystem fs,
                                       Path path,
                                       byte[] family,

                                throws java.io.IOException

Create an HFile with the given number of rows between a given start key and end key @ family:qualifier. The value will be the key value. This cells will also have a tag whose value is the key.

Throws:

java.io.IOException

createHFile

public static void createHFile(Configuration configuration,
                               FileSystem fs,
                               Path path,
                               DataBlockEncoding encoding,

                        throws java.io.IOException

Create an HFile with the given number of rows between a given start key and end key @ family:qualifier. If withTag is true, we add the rowKey as the tag value for tagtype ACL_TAG_TYPE

Throws:

java.io.IOException

verifyTags

public static void verifyTags(Table table)
                       throws java.io.IOException

This verifies that each cell has a tag that is equal to its rowkey name. For this to work the hbase instance must have HConstants.RPC_CODEC_CONF_KEY set to KeyValueCodecWithTags.class.getCanonicalName());

Parameters:

table - table containing tagged cells

Throws:

java.io.IOException - if problems reading table
