(HADOOP-9307) > We suggest setting dfs.client.read.shortcircuit.buffer.size to a value that > is very close to what we'd set it to anyway, without clearly explaining why > this is important. > There are other properties that we claim are important, but we don't offer > any suggestions or explanations. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
