Duong updated HDDS-10382:
-------------------------
Description:
Add "-Dorg.apache.ratis.thirdparty.io.netty.tryReflectionSetAccessible=true" to
the ozone script to allow Netty unsafe memory allocation.
According to Netty doc.
{quote}When a new {{java.nio.ByteBuffer}} is allocated, its content is filled
with zeroes. This "zeroing" consumes CPU cycles and memory bandwidth. Normally,
the buffer is then immediately filled from some data source, so the zeroing did
no good.
