Aravindan Vijayan created HDDS-2151:
---------------------------------------
Summary: Ozone client prints the entire request payload in DEBUG
level.
Key: HDDS-2151
URL: https://issues.apache.org/jira/browse/HDDS-2151
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Aravindan Vijayan
In XceiverClientRatis.java:221, we have the following snippet where we have a
DEBUG line that prints out the entire Container Request proto.
{code}
ContainerCommandRequestProto finalPayload =
ContainerCommandRequestProto.newBuilder(request)
.setTraceID(TracingUtil.exportCurrentSpan())
.build();
boolean isReadOnlyRequest = HddsUtils.isReadOnly(finalPayload);
ByteString byteString = finalPayload.toByteString();
LOG.debug("sendCommandAsync {} {}", isReadOnlyRequest, finalPayload);
return isReadOnlyRequest ?
getClient().sendReadOnlyAsync(() -> byteString) :
getClient().sendAsync(() -> byteString);
{code}
This causes OOM while writing large (~300MB) keys.
{code}
