Creates Builder with cache configuration disabled

方法详细资料

withOutputDir

public StoreFileWriter.Builder withOutputDir(org.apache.hadoop.fs.Path dir)

Use either this method or withFilePath(org.apache.hadoop.fs.Path), but not both.

参数:

dir - Path to column family directory. The directory is created if does not exist. The file is given a unique name within this directory.

返回:

this (for chained invocation)

withFilePath

public StoreFileWriter.Builder withFilePath(org.apache.hadoop.fs.Path filePath)

Use either this method or withOutputDir(org.apache.hadoop.fs.Path), but not both.

参数:

filePath - the StoreFile path to write

返回:

this (for chained invocation)

withFavoredNodes

public StoreFileWriter.Builder withFavoredNodes(InetSocketAddress[] favoredNodes)

参数:

favoredNodes - an array of favored nodes or possibly null

返回:

this (for chained invocation)

withComparator

public StoreFileWriter.Builder withComparator(CellComparator comparator)

withBloomType

public StoreFileWriter.Builder withBloomType(BloomType bloomType)

withMaxKeyCount

public StoreFileWriter.Builder withMaxKeyCount(long maxKeyCount)

参数:

maxKeyCount - estimated maximum number of keys we expect to add

返回:

this (for chained invocation)

withFileContext

public StoreFileWriter.Builder withFileContext(HFileContext fileContext)

withShouldDropCacheBehind

public StoreFileWriter.Builder withShouldDropCacheBehind(boolean shouldDropCacheBehind)

build

public StoreFileWriter build()
                      throws IOException

Create a store file writer. Client is responsible for closing file when done. If metadata, add BEFORE closing using StoreFileWriter.appendMetadata(long, boolean).

抛出:

IOException
