Manukranth Kolloju commented on HBASE-8206:
-------------------------------------------
Are there any compiler optimizations that you know of which might trivially
convert :
if (codec == null) {
synchronized (lock) {
if (codec == null)
{
GzipCodec tmpCodec = new ReusableStreamGzipCodec();
tmpCodec.setConf(new Configuration(conf));
codec = tmpCodec;
}
}
to :
if (codec == null) {
synchronized (lock) {
if (codec == null)
{
codec = new ReusableStreamGzipCodec();
codec.setConf(new Configuration(conf));
}
}
> Thread safety issues with Compression.Algorithm.GZ and SNAPPY

> The Compression.Algorithm was not completely thread safe. Hence making it
> thread safe. Trying to fix this the same way it was fixed in HBase
> trunk(HBASE-5458) with a minor change since the fix in trunk is not
> completely thread safe.
