executing scan -t table returns no result despite tablet server showing 110K entries : I am facing an issue when trying to scan an accumulo table. Short environment abstract:  
Localhost single cluster setup of all involved components: 

 - accumulo 1.8.0
 - zookeeper 3.4
 - hadoop 2.7.3  

OS:  

 - Ubuntu 16.05, 64 bit

Java:

 - 1.8.0_111-8u111-b14-2ubuntu0.16.04.2-b14

To the isssue.  
First I created a user and then crete a table with that user as owner. I was able to insert data into the table using a Java client.  
Later I wanted to check what I had inserted and for simplicity sake I chose the accumulo shell.  
When I run  the command scan -t <table>, it returns immediately, giving me no results. Now the funny thing is, that the tablet status window (localhost:9995) shows that the table in questions has approx 110K entries.[The tablet server status screenshot][1]

Next I checked the size of the tablets in hdfs. The size implies to me that there is data:  
`1062429 2016-12-15 23:19 /accumulo/tables/c/default_tablet/A000001t.rf`  
Another table where I have the same issue has an even larger rf file (it has even more entries):  
`12433646 2016-12-15 22:23 /accumulo/tables/a/default_tablet/A000000i.rf`  
  
Next I turned on the debug mode in the shell:  
`debug on`  
Then I run the scan command again. The output:  
`scan

To me the output looks good as to say the scan command finds the table and the tablet belonging to that table. But no result is shown.  
  
Any insight on what I am doing wrong or missing would be appreciated.
