Ambari HDFS File view - File Preview for snappy file

David_Tam — Mon, 19 Aug 2019 10:12:49 GMT

Hello I am trying to get File Preview for snappy files to work in Ambari -> HDFS Files. Could it be made to work? I assume it could because it seems to try decoding but failed in finding the snappy codec.

This is running on a 2.3.4 sandbox. I am getting:

500 native snappy library not available: this version of libhadoop was built without snappy support.

I have tried a few things:

Adding snappy natives to LD_LIBRARY_PATH in /etc/profile

Linking snappy jars into ambari server lib:

cd /usr/lib/ambari-server/

ln -s /usr/hdp/current/hadoop-client/lib/snappy-java-1.0.4.1.jar  .

But I am still getting the same error.

Any ideas would be great! Thanks!

@David Tam Take a look at this HCC question and see if it applies. https://community.hortonworks.com/questions/18903/this-version-of-libhadoop-was-built-without-snappy.html. Most likely need to add the snappy.jar to class\library path in the Ambari config.

Thanks Scott yes this is what I think as well and therefore I have Linked snappy jars into ambari server lib.

re the HCC questions you posted - that has helped me earlier and I was able to save out RDD in spark as compressed snappy file, but how do you make ambari HDFS Files vlew to use the snappy lib (I can only think of LD_LIBRARY_PATH or java classpath)

@David Tam

Can you try adding native dir in AMBARI_JVM_ARGS variable and see if that resolve this.

File: /var/lib/ambari-server/ambari-env.sh

-Djava.library.path=/usr/hdp/<version>/hadoop/lib/native

@Jitendra Yadav - yes this has works thanks!

This is how the process looks like when I run ps:

root     17484     1 99 13:47 pts/0    00:00:59 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/bin/java -server -XX:NewRatio=3 -XX:+UseConcMarkSweepGC -XX:-UseGCOverheadLimit -XX:CMSInitiatingOccupancyFraction=60 -Dsun.zip.disableMemoryMapping=true -Xms512m -Xmx2048m -Djava.security.auth.login.config=/etc/ambari-server/conf/krb5JAASLogin.conf -Djava.security.krb5.conf=/etc/krb5.conf -Djavax.security.auth.useSubjectCredsOnly=false -Djava.library.path=/usr/hdp/current/hadoop-client/lib/native -cp /etc/ambari-server/conf:/usr/lib/ambari-server/*:/usr/share/java/postgresql-jdbc.jar org.apache.ambari.server.controller.AmbariServer

It seems setting -Djava.library.path is the only thing required - I have subsequently remove the snappy link in /usr/lib/ambari-server/ and can confirm it still works.
