-Be aware that a small documentation bug exists with the compact command in the

+### Silent data-loss via bulk imported files
 
-## Highlights
+A user recently reported that a simple bulk-import application would
+occasionally lose some records. Through investigation, it was found that when
+bulk imports into a table failed the initial assignment, the logic that
+automatically retries the imports was incorrectly choosing the tablets to
+import the files into. [ACCUMULO-3967][ACCUMULO-3967] contains more information
+on the cause and identification of the bug. The data-loss condition would only
+affect entire files. If records from a file exist in Accumulo, it is still
+guaranteed that all records within that imported file were successful.
+
+As such, users who have bulk import applications using previous versions of
+Accumulo should verify that all of their data was correctly ingested into
+Accumulo and immediately update to Accumulo 1.7.1 (This is the same bug that
+was fixed in 1.6.4, so you won't be affected if you're running 1.6.4 or newer).

+possible failure). To reduce false positives, such as those which can occur
+with systemd's extra cgroup mounts in CentOS7, an additional check was added to
