Description
CASSANDRA-15884 added logic to detect if the native lib of lz4 was properly loaded and to log a warning if this was not the case, it seems that the catch for this didn’t handle the class loading issue that also happens in this case.
ERROR [main] 2020-07-07 22:49:32,560 CassandraDaemon.java:800 - Exception encountered during startup java.lang.NoClassDefFoundError: Could not initialize class net.jpountz.lz4.LZ4JNI at net.jpountz.lz4.LZ4JNICompressor.compress(LZ4JNICompressor.java:36) at net.jpountz.lz4.LZ4Factory.<init>(LZ4Factory.java:207) at net.jpountz.lz4.LZ4Factory.instance(LZ4Factory.java:51) at net.jpountz.lz4.LZ4Factory.nativeInstance(LZ4Factory.java:91) at org.apache.cassandra.service.StartupChecks.lambda$static$0(StartupChecks.java:149) at org.apache.cassandra.service.StartupChecks.verify(StartupChecks.java:127) at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:211) at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:661) at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:778)
After patching, the following is the behavior
WARN [main] 2020-07-07 22:50:45,018 StartupChecks.java:153 - lz4-java was unable to load native libraries; this will lower the performance of lz4 (network/sstables/etc.): Could not initialize class net.jpountz.lz4.LZ4JNI
