Difference between DataFrame.cache() and hiveContext.cacheTable()?

[Sahil Sareen]

Is there any difference between the following snippets:

val df = hiveContext.createDataFrame(rows, schema)
df.registerTempTable("myTable")
df.cache()

and

val df = hiveContext.createDataFrame(rows, schema)
df.registerTempTable("myTable")
hiveContext.cacheTable("myTable")
