------------------------------
Yeah. This is actually a pain. Master splitting WALs used to be creating blockcaches until ugly-hacked it not too.

stack commented on HBASE-4932:
------------------------------
I was going to say this is probably really expensive but its just cloning of in memory Arrays and Properties so probably not too bad:
{code}
- public static final WriterFactory getWriterFactory(Configuration conf) {
- return HFile.getWriterFactory(conf, new CacheConfig(conf));
+ public static final WriterFactory getWriterFactoryNoCache(Configuration
+ conf) {
+ Configuration tempConf = new Configuration(conf);
+ tempConf.setFloat(CacheConfig.HFILE_BLOCK_CACHE_SIZE_KEY, 0.0f);
+ return HFile.getWriterFactory(conf, new CacheConfig(tempConf));
{code}
+1 on patch.
