方法的具体详情如下:
包路径:org.apache.hadoop.util.Shell
类名称:Shell
方法名:getHadoopHomeDir
[英]Get the Hadoop home directory. If it is invalid, throw an exception.
[中]获取Hadoop主目录。如果无效,则抛出异常。
代码示例来源:origin: org.apache.hadoop/hadoop-common
/**
* Get the Hadoop home directory. Raises an exception if not found
* @return the home dir
* @throws IOException if the home directory cannot be located.
*/
public static String getHadoopHome() throws IOException {
return getHadoopHomeDir().getCanonicalPath();
}
代码示例来源:origin: org.apache.hadoop/hadoop-common
/**
* Fully qualify the path to a binary that should be in a known hadoop
* bin location. This is primarily useful for disambiguating call-outs
* to executable sub-components of Hadoop to avoid clashes with other
* executables that may be in the path. Caveat: this call doesn't
* just format the path to the bin directory. It also checks for file
* existence of the composed path. The output of this call should be
* cached by callers.
*
* @param executable executable
* @return executable file reference
* @throws FileNotFoundException if the path does not exist
*/
public static File getQualifiedBin(String executable)
throws FileNotFoundException {
// construct hadoop bin path to the specified executable
return getQualifiedBinInner(getHadoopHomeDir(), executable);
}
