【Hive】ERROR exec.DDLTask: java.lang.UnsatisfiedLinkError: org.apache.hadoop.util.NativeCrc32.nati...

1/在$HADOOP_HOME/lib/native下面放了2.5.0-native-snappy.tar.gz，这是HDFS存储压缩所需的本地lib包。
cd ~/app/hadoop-2.5.0-cdh5.3.6/lib/native/

2/执行命令hadoop checknative

18/06/23 07:23:36 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Native library checking:
hadoop:  true
zlib:    true
snappy:  true
lz4:     true
bzip2:   true
openssl: false

3/但是， hive命令进入hive的命令行，执行show tables之类的操作时，报如下错误：

ERROR exec.DDLTask: java.lang.UnsatisfiedLinkError: org.apache.hadoop.util.NativeCrc32.nativeComputeChunkedSumsByteArray(II[BI[BIILjava/lang/String;JZ)V

4/原因：由于放入的lib包版本问题，暂时先把它们删除吧。
再次进入hive中，执行命令OK。

5/执行hive -hiveconf hive.root.logger=DEBUG,console，发现还是有错误。
暂时没有去解决，但是不影响功能。
