{code:java|title=Compression.java} // data input buffer size to absorb small reads from application. private static final int DATA_IBUF_SIZE = 1 * 1024; // data output buffer size to absorb small writes from application. private static final int DATA_OBUF_SIZE = 4 * 1024; {code} There exists these hard coded buffer sizes in the Compression code. Instead, use the JVM default sizes, which, this day and age, are usually set for 8K. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
