Erik Krogen commented on HDFS-12976:
------------------------------------
Hey [~csun], one follow-up question about these two lines:
{code}
alignmentContext = new ClientGSIContext();
((ClientHAProxyFactory<T>) factory).setAlignmentContext(alignmentContext);
{code}
Is there any danger of overwriting another proxy's AlignmentContext with these
lines? Will the same factory be re-used across multiple clients? I am wondering
if it would be more appropriate to check if the factory already has an
AlignmentContext, and if so re-use that one instead of creating a new one.
