difference between = = and JavaScala's = = follows the comparison rules:First check whether the left side is null, if not, call the left manipulation data of the Equals method. Therefore, the exact comparison depends on the definition of the Equals method that makes the operation. Because of the automatic null check, there is no need to manually check it again.java = = can compare primitive types or reference types. For primitive types, the equality of the = = Comparison values for
First, the commonly compiled Hadoop library is in Lib, if you do not want to compile, you can use the lib/native inside the precompiled library, and then move the native library to the Lib folder.CP hadoop-2.6.0/lib/native/* hadoop-2.6.0/lib/Second, add the system variableExport Hadoop_common_lib_native_dir=/home/administrator/work/hadoop-2.6.0/lib/nativeexport H

. According to the function of the Division: node flow and packaging flow.four basic streams : Byte input stream, byte output stream, character output stream, character input stream
BYTE stream
Character Stream
Output stream

The four basic streams are abstract classes : The other flows are inherited from the four main classes.We cannot create four base stre
My solution is:
Don't use xwork-2.1.6.jar, for xwork-2.1.2.jar!
