lz4 upgrade

[guoliangxue01]

Hi Ignite Team,

org.lz4 has been moved to lz4-java. If I use ignite-compress (2.16.0) where org.lz4 has been removed, but the class CompressionProcessorImpl (2.16.0) in the ignite is still using org.lz4 to compress, which leads to

Caused by: java.lang.NoClassDefFoundError: net/jpountz/lz4/LZ4Factory igniteserver-1 | at org.apache.ignite.internal.processors.compress.CompressionProcessorImpl$Lz4.(CompressionProcessorImpl.java:429) igniteserver-1 | at org.apache.ignite.internal.processors.compress.CompressionProcessorImpl.maxCompressedBufferSize(CompressionProcessorImpl.java:419) igniteserver-1 | at org.apache.ignite.internal.processors.compress.CompressionProcessorImpl.(CompressionProcessorImpl.java:56)

do you have any plan to upgrade it to lz4-java as well?

• ignite-compress 2.16 depends on lz4-java: https://central.sonatype.com/artifact/org.apache.ignite/ignite-compress/dependencies
• net.jpountz.lz4.LZ4Factory is part of lz4-java: https://github.com/lz4/lz4-java/blob/master/src/java/net/jpountz/lz4/LZ4Factory.java

It works as expected, please make sure you have lz4-java in classpath.
