Failure of kuromoji plugin installation.
kurimoji is the Japanese Analysis plugin. elasticsearch 2.1 integrates this plugin as official.
So, this plugin can be installed using the plugin manager.
sudo /usr/share/elasticsearch/bin/plugin install --verbose analysis-kuromoji Failed: SSLException[java.security.ProviderException: java.security.KeyException]; nested: ProviderException[java.security.KeyException]; nested: KeyException; ERROR: failed to download out of all possible locations
But, in my environment, plugin installation failed.
Switch Java Version
The cause of the failure is java version.
so, I checked java version.

There is java-1.8.0-openjdk.
Next, check using java version.
alternatives --config java There are 2 programs which provide 'java'. Selection Command ----------------------------------------------- 1 /usr/lib/jvm/jre-1.5.0-gcj/bin/java *+ 2 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
java-1.8.0-openjdk is not installed.
I will install it.
sudo yum install -y java-1.8.0-openjdk
check using java version.
java -version java version "1.7.0_91"
Java version is still not changed. I will switch java version.
sudo alternatives --config java There are 3 programs which provide 'java'.

I check using java version again.
java -version openjdk version "1.8.0_65" OpenJDK Runtime Environment (build 1.8.0_65-b17) OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)
Version was changed to java-1.8.0-openjdk.
Reinstallation of kurimoji plugijn
On java-1.8.0-openjdk, bin/plugin command executes again.

It worked out.
just in case, I will check installed plugin.

It worked out.
Conclusion
On elasticsearch2.1.1, if you want to execute plugin command, you must update to java version 8.
Once installed, you can use by java version 7.
But I recommend that you makes your app environment latest. update work is very important.
