Interpreter %sq not found Zeppelin swallows last "l" for some reason...?

[Serega Sheypak]

Hi, I get super weird exception:

ERROR [2017-06-26 07:44:17,523] ({qtp2016336095-99}
NotebookServer.java[persistAndExecuteSingleParagraph]:1749) - Exception
from run

org.apache.zeppelin.interpreter.InterpreterException:
paragraph_1498480084440_1578830546's Interpreter %sq not found

I have three paragraphs in my notebook



%spark.dep

z.load("my.local.jar.jar")


%spark

import com.myorg.SuperClass

// bla-bla

features.toDF().registerTempTable("features")


%sql

select f1, f2, count(*) as cnt from features;


The last one gets this weird exception. Where did "l" go?
