Key: HDFS-15284
URL: https://issues.apache.org/jira/browse/HDFS-15284
Project: Hadoop HDFS
Issue Type: New Feature
Components: hdfs
Affects Versions: 3.4.0

*2.Configure JDK*
Place bcprov-ext-jdk15on-165.jar in $JAVA_HOME/jre/lib/ext directory,
add "security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider"
to $JAVA_HOME/jre/lib/security/java.security file
*3.Configure Hadoop KMS*
*4.test HDFS sm4*
hadoop key create key1 -cipher 'SM4/CTR/NoPadding'
hdfs dfs -mkdir /benchmarks
